2A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
3Single-cell RNA-seq highlights intra-tumoral heterogeneity and malignant progression in pancreatic ductal adenocarcinoma显示文摘Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer featured with high intra-tumoral heterogeneity and poor prognosis. To comprehensively delineate the PDAC intra-tumoral heterogeneity and the underlying mechanism for PDAC progression, we employed single-cell RNA-seq (scRNA-seq) to acquire the transcriptomic atlas of 57,530 individual pancreatic cells from primary PDAC tumors and control pancreases, and identified diverse malignant and stromal cell types, including two ductal subtypes with abnormal and malignant gene expression profiles respectively, in PDAC. We found that the heterogenous malignant subtype was composed of several subpopulations with differential proliferative and migratory potentials. Cell trajectory analysis revealed that components of multiple tumor-related pathways and transcription factors (TFs) were differentially expressed along PDAC progression. Furthermore, we found a subset of ductal cells with unique proliferative features were associated with an inactivation state in tumor-infiltrating T cells, providing novel markers for the prediction of antitumor immune response. Together, our findings provide a valuable resource for deciphering the intra-tumoral heterogeneity in PDAC and uncover a connection between tumor intrinsic transcriptional state and T cell activation, suggesting potential biomarkers for anticancer treatment such as targeted therapy and immunotherapy.Junya Peng Bao-Fa Sun Chuan-Yuan Chen Jia-Yi Zhou Yu-Sheng Chen Hao Chen Lulu Liu Dan Huang Jialin Jiang Guan-Shen Cui Ying Yang Wenze Wang Dan Guo Menghua Dai Junchao Guo Taiping Zhang Quan Liao Yi Liu Yong-Liang Zhao Da-Li Han Yupei Zhao Yun-Gui Yang Wenming Wu 2019Cell Research2019,29,9:24
4Epidemiological and risk analysis of the H7N9 subtype influenza outbreak in China at its early stage显示文摘Dozens of human cases infected with H7N9 subtype avian influenza virus (AIV) have been confirmed in China since March, 2013. Distribution data of sexes, ages, professions and regions of the cases were analyzed in this report. The results showed that the elderly cases, especially the male elderly, were significantly more than expected, which is different from human cases of H5N1 avian influenza and human cases of the pandemic H1N1 influenza. The outbreak was rated as a Grade Ⅲ (severe) outbreak, and it would evolve into a Grade IV (very severe) outbreak soon, using a method reported previously. The H7N9 AIV will probably circulate in humans, birds and pigs for years. Moreover, with the driving force of natural selection, the virus will probably evolve into highly pathogenic AIV in birds, and into a deadly pandemic influenza virus in humans. Therefore, the H7N9 outbreak has been assumed severe, and it is likely to become very or extremely severe in the future, highlighting the emergent need of forceful scientific measures to eliminate any infected animal flocks. We also described two possible mild scenarios of the future evolution of the outbreak.ZHUANG QingYe WANG SuChun WU MeiLi LIU Shuo JIANG WenMing HOU GuangYu LI JinPing WANG KaiCheng YU JianMin CHEN JiMing CHEN JiWang 2013Chinese Science Bulletin2013,58,26:18
5The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence.Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li 2023Science China(Physics,Mechanics & Astronomy)2023,66,8:14
6Efficient generation of transgenic chickens using the spermatogonial stem cells in vivo and ex vivo transfection显示文摘The highly efficient novel methods to produce transgenic chickens were established by directly in-jecting the recombinant plasmid containing green fluorescent protein (GFP) gene into the cock's testis termed as testis-medianted gene transfer (TMGT), and transplanting transfected spermatogonial stem cells (TTSSCs). For the TMGT approach,four dosages of pEGFP-N1 DNA/cationic polymer complex were injected intratesticularly. The results showed: (1) 48 h after the injection,the percentages of testis cells expressing GFP were 4.0%, 8.7%, 10.2% and 13.6% in the 50, 100, 150 and 200 μg/mL group, re-spectively. The difference from the four dosage groups was significant (P<0.05). On day 25 after the injection, a dosage-dependent and time-dependent increase in the number of transgenic sperm was observed. The percentages of gene expression reached the summit and became stable from day 70 to 160, being 12.7%, 12.8%, 15.9% and 19.1%, respectively. The difference from the four dosage groups was also significant (P<0.05). (2) 70 d after the injection, strong green fluorescent could be observed in the seminiferous tubules by whole-mount in-situ hybridization. (3) 70 d after the injection, the semen was collected and used to artificially inseminate wild-type females. The blastoderms of F1 and F2 transgenic chicken expressed GFP were 56.2% (254/452) and 53.2% (275/517), respectively. The detec-tion of polymerase chain reaction (PCR) of F1 and F2 transgenic chicken blood genomic DNA showed that 56.5% (3/23) of F1 and 52.9% (9/17) of F2 were positive. Southern blot showed GFP DNA was in-serted in their genomic DNAs. (4) Frozen whole mount tissue sections of F1 and F2 transgenic chicken liver, heart, kidney and muscle showed that the rates of green fluorescent positive were between 50.0% and 66.7%. (5) With the TTSSCs method, SSCs ex vivo transfected with GFP were transplanted into recipient roosters whose endogenic SSCs had been resoluted. The donor SSCs settled and GFP ex-pression became readily detectable in the frozen whole mount tissue sections of recepient testes. Moreover, sperms carrying GFP could be produced normally. The results of artificially inseminating wild-type females with these sperms showed 12.5% (8/64) of offspring embryo expressed GFP and 11.1% (2/18) hatched chicks were tested transgenic. Our data therefore suggest TMGT and TTSSCs are the feasible methods for the generation of transgenic chickens.LI BiChun SUN GuoBo SUN HuaiChang XU Qi GAO Bo ZHOU GuanYue ZHAO WenMing WU XinSheng BAO WenBin YU Fei WANG KeHua CHEN GuoHong 2008Science China(Life Sciences)2008,51,8:13

8Transcriptional Regulation of miR528 by OsSPL9 Orchestrates Antiviral Response in Rice显示文摘Many microRNAs (miRNAs) are critical regulators of plant antiviral defense.However,little is known about how these miRNAs respond to virus invasion at the transcriptional level.We previously show that defense against Rice stripe virus (RSV) invasion entailed a reduction of miR528 accumulation in rice,alleviating miR528-mediated degradation of L-Ascorbate Oxidase (AO) mRNA and bolstering the antiviral activity of AO.Here we show that the miR528-A0 defense module is regulated by the transcription factor SPL9.SPL9 displayed high-affinity binding to specific motifs within the promoter region of miR528 and activated the expression of miR528 gene in vivo.Loss-of-function mutations in SPL9 caused a significant reduction in miR528 accumulation but a substantial increase of AO mRNA,resulting in enhanced plant resistance to RSV.Conversely,transgenic overexpression of SPL9 stimulated the expression of miR528 gene,hence lowering the level of AO mRNA and compromising rice defense against RSV.Importantly,gain in RSV susceptibility did not occur when SPL9 was overexpressed in mir528 loss-of-function mutants,or in transgenic rice expressing a miR528-resistant AO.Taken together,the finding of SPL9-mediated transcriptional activation of miR528 expression adds a new regulatory layer to the miR528-A0 antiviral defense pathway.Shengze Yao Zhirui Yang Rongxin Yang Yu Huang Ge Guo Xiangyue Kong Ying Lan Tong Zhou He Wang Wenming Wang Xiaofeng Cao Jianguo Wu Yi Li 2019Molecular Plant2019,12,8:10
9Characteristics of fecal microbiota in non-alcoholic fatty liver disease patients显示文摘This study was designed to investigate the gut microbiota of patients with non-alcoholic fatty liver disease. The inclusive and exclusive criteria for NAFLD patients and healthy subjects were formulated, and detailed clinical data were collected. The genomic DNA of stool samples were extracted for 16 S r DNA sequencing, and the amplified V4-region was sequenced on the Illumina Miseq platform. Metastats analysis was performed to identify the differential taxa between the groups. Redundancy analysis was used to evaluate the association between gut microbial structure and clinical variables. Thirty NAFLD patients and37 healthy controls were involved. The 16 S r DNA sequencing showed that there was a dramatic variability of the fecal microbiota among all the individuals. Metastats analysis identified eight families and 12 genera with significant differences between the two groups. When some clinical parameters, such as waist-to-hip ratio(WHR) and homeostasis model assessment of insulin resistance(HOMA-IR), were enrolled in Redundancy analysis, the distribution of the two group of samples was obviously changed. The compositional shifts in fecal bacterial communities of NAFLD patients from the healthy controls were mainly at family or genus levels. According to our Redundancy analysis, insulin resistance and obesity might be closely related to both NAFLD phenotype and intestinal microecology.Fan Li Gang Sun Zikai Wang Wenming Wu He Guo Lihua Peng Lili Wu Xu Guo Yunsheng Yang 2018Science China(Life Sciences)2018,61,7:9
10Real-world study of surgical treatment of pancreatic cancer in China: annual report of China Pancreas Data Center (2016-2020)显示文摘Objective: In 2015, the Chinese Pancreatic Association of the Chinese Society of Surgery of the Chinese Medical Association launched a national multicenter online system for registration of surgical treatment of pancreatic cancer in China, called China Pancreas Data Center (CPDC). With continued effort, the CPDC has developed over time. Herein, we report the general results of the CPDC from January 2016 to January 2020 to present the real-world situation of surgical treatment of pancreatic cancer in China.Methods: The data of the CPDC from January 2016 to January 2020 were retrieved and analyzed in this real-world study, including the data on patient demographics, comorbidities, diagnostic modalities, neoadjuvant treatment, surgical procedures, postoperative complications and treatment, pathological examinations, postoperative adjuvant treatment, survival, and risk factors.Results: A total of 13,595 cases from 70 centers in 28 provinces were retrieved for analysis. This study reported the largest cohort of patients who underwent surgical treatment for pancreatic cancer in China to date. More cases were derived from the Eastern regions, among which Shanghai, Beijing, and Zhejiang ranked in the top three. The peak age of the patients ranged from 60 to 69 years. The ratio of males to females was 1.5:1. Overall, 64.3% of the tumors were located in the head and neck of the pancreas, and 35.7% in the body and tail of the pancreas. Of the patients, 23.0% underwent positron-emission tomography-computed tomography, 21.6% underwent endoscopic ultrasound, and 4.8% underwent preoperative biopsy. Two percent of the patients underwent neoadjuvant treatment, while 68.9% underwent R0 surgical resection (margin free of tumor cells). Of the latter, 78.6% of the operations were open procedures, 12.6% were laparoscopic procedures, 2.9% were robotic procedures, and 3.7% were converted to open procedures. The in-hospital mortality rate after surgery was 0.4%. The incidence of grade 2 and grade 3 postoperative pancreatic fistulas was 25.5% and 2.5%, respectively. The incidence of complications based on the Clavien-Dindo classification was 17.9% of grade II, 4.3% of grade IIIa, 1% of grade IIIb, and 0.6% of grade IV. Of the patients, 28.9% underwent postoperative adjuvant chemotherapy. The 1-year, 2-year, and 3-year overall survival of these patients were 77%, 51%, and 38%, respectively. In the 8542 patients who underwent R0 resection, the 1-year, 2-year, and 3-year overall survival and disease-free survival were 77% , 54%, and 43%, and 68%, 49%, and 41%, respectively. The factors related to the prognosis of these patients were also identified after uni-and multi-variate analyses.Conclusion: The surgical quality, safety, and long-term survival of the patients in CPDC are similar to those of international high-volume pancreatic centers. However, neoadjuvant and postoperative adjuvant chemotherapy should be improved.Wenming Wu Yi Miao Yinmo Yang Wenhui Lou Yupei Zhao 2022Journal of Pancreatology2022,5,1:7

12Genetic analysis and fine mapping of an enclosed panicle mutant esp2 in rice (Oryza sativa L.)显示文摘The phenomenon of panicle enclosure in rice is mainly caused by the shortening of uppermost internode.Elucidating the molecular mechanism of panicle enclosure will be helpful for solving the problem of panicle enclosure in male sterile lines and creating new germplasms in rice.We acquired a monogenic recessive enclosed panicle mutant,named as esp2 (enclosed shorter panicle 2),from the tissue culture progeny of indica rice cultivar Minghui-86.In the mutant,panicles were entirely enclosed by flag leaf sheaths and the uppermost internode was almost completely degenerated,but the other internodes did not have obvious changes in length.Genetic analysis indicated that the mutant phenotype was controlled by a recessive gene,which could be steadily inherited and was not affected by genetic background.Apparently,ESP2 is a key gene for the development of uppermost internode in rice.Using an F 2 population of a cross between esp2 and a japonica rice cultivar Xiushui-13 as well as SSR and InDel markers,we fine mapped ESP2 to a 14-kb region on the end of the short arm of chromosome 1.According to the rice genome sequence annotation,only one intact gene exists in this region,namely,a putative phosphatidylserine synthase gene.Sequencing analysis on the mutant and the wild type indicated that this gene was inserted by a 5287-bp retrotransposon sequence.Hence,we took this gene as a candidate of ESP2.The results of this study will facilitate the cloning and functional analysis of ESP2 gene.GUAN HuaZhong DUAN YuanLin LIU HuaQing CHEN ZhiWei ZHUO Ming ZHUANG LiJun QI WenMing PAN RunSen MAO DaMei ZHOU YuanChang WANG Feng WU WeiRen 2011Chinese Science Bulletin2011,56,14:6
13Design,modeling and experimental investigation of a magnetically modulated rotational energy harvester for low frequency and irregular vibration显示文摘Vibration energy harvesting is a promising approach for sustainable energy generation from ambience to meet the development of self-powered systems.Here,we propose a novel compact non-resonant magnetically modulated rotational energy harvester(MMR-EH)for low frequency and irregular vibration.Through the rational arrangement of multiple magnetic fields in space,a ring route with low potential energy is established.A movable magnet can be non-contact modulated by the magnetic force to move along the ring route under irregular vibration,which is instrumental in electromechanical energy conversion.A dynamic model of the MMR-EH is developed based on the energy method and verified experimentally.The effects of key parameters on the magnetically modulated route are analysed.The simulation and experimental results demonstrate that the MMR-EH can effectively harvest the energy from ultra-low frequency(3 Hz)and irregular vibration.At a reciprocating vibration frequency of 10 Hz and an amplitude of 20 mm,the harvester can produce an average power of 0.29 mW.ZHAO LinChuan ZOU HongXiang GAO QiuHua YAN Ge WU ZhiYuan LIU FengRui WEI KeXiang YANG Bin ZHANG WenMing 2020Science China(Technological Sciences)2020,63,10:5
14Bortezomib, dexamethasone plus thalidomide for treatment of newly diagnosed multiple myeloma patients with or without renal impairment显示文摘Objective: To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM) with or without renal impairment receiving the therapy of bortezomib, dexamethasone plus thalidomide (BTD) regimen in order to analyze the effects of BTD regimen on the prognosis of the MM patients with renal impairment compared with the patients without renal impairment. Methods: Seventy-two newly diagnosed MM patients entered into our study and all the patients belonged to International Stage System (ISS) 3 in which transplantation patients were excluded or the patients refused receiving transplantation therapy. According to the level of serum creatinine (Scr), the patients were divided into two groups including group 1 (n=42) (Scr <2 mg/dL) and group 2 (n=30) (Scr ≥2 mg/dL). All the patients received the therapy of BTD regimen as induction therapy, and the median treatment time was 5 (range, 2-8) cycles. The outcome was analyzed retrospectively. Results: The overall remission (OR) rates were 81.0% (group 1) and 80.0% (group 2). There was no statistical difference between the two groups (P>0.05). In group 2, 10 patients (33.3%) got renal function reversal, 14 patients (46.7%) got improved renal function and the median time to renal function reversal was 1.4 (range, 0.7-3.0) months. Among 12 patients with hemodialysis at diagnosis, 8 patients got rid of hemodialysis after median 4 cycles of therapy (range, 3-6 cycles). After a median follow-up period of 16 (range, 2-31) months, 5 patients (11.9%) in group 1 died and 9 patients (30.0%) in group 2 died (P=0.056). The 2-year estimate of overall survival was 77.3% in group 1 and 63.8% in group 2, respectively (P=0.188). During a median follow-up time of 13.0 months (range, 2-25 months), 15 patients (35.7%) in group 1 progressed and 13 patients (43.3%) in group 2 progressed (P=0.513). The 2-year estimate of response duration was 50.6% in group 1 and 42.1% in group 2, respectively (P=1). The main toxicities in the two groups included thrombocytopenia, peripheral neuropathy (PN), infection, herpes zoster and so on. The incidence of grade 3 and 4 adverse events was low. Conclusions: BTD regimen may become the front-line therapy for the newly diagnosed MM patients with renal impairment because BTD regimen can improve the prognosis of the patients with renal impairment as good as the patients without renal impairment.Guangzhong Yang Wenming Chen Yin Wu 2013Chinese Journal of Cancer Research2013,25,2:5
15A Fiber Tractography Study of Social-Emotional Related Fiber Tracts in Children and Adolescents with Autism Spectrum Disorder显示文摘The symptoms of autism spectrum disorder(ASD) have been hypothesized to be caused by changes in brain connectivity. From the clinical perspective, the‘‘disconnectivity'' hypothesis has been used to explain characteristic impairments in ‘‘socio-emotional'' function.Therefore, in this study we compared the facial emotional recognition(FER) feature and the integrity of socialemotional-related white-matter tracts between children and adolescents with high-functioning ASD(HFA) and their typically developing(TD) counterparts. The correlation between the two factors was explored to find out if impairment of the white-matter tracts is the neural basis of social-emotional disorders. Compared with the TD group,FER was significantly impaired and the fractional anisotropy value of the right cingulate fasciculus was increased in the HFA group(P \ 0.01). In conclusion, the FER function of children and adolescents with HFA was impaired and the microstructure of the cingulate fasciculus had abnormalities.Yun Li Hui Fang Wenming Zheng Lu Qian Yunhua Xiao Qiaorong Wu Chen Chang Chaoyong Xiao Kangkang Chu Xiaoyan Ke 2017Neuroscience Bulletin2017,33,6:5

18Confined Ni-In intermetallic alloy nanocatalyst with excellent coking resistance for methane dry reforming显示文摘Carbon dioxide and methane are two main greenhouse gases which are contributed to serious global warming.Fortunately,dry reforming of methane(DRM),a very important reaction developed decades ago,can convert these two major greenhouse gases into value-added syngas or hydrogen.The main problem retarding its industrialization is the seriously coking formation upon the nickel-based catalysts.Herein,a series of confined indium-nickel(In-Ni)intermetallic alloy nanocatalysts(In_(x)Ni@SiO_(2))have been prepared and displayed superior coking resistance for DRM reaction.The sample containing 0.5 wt.%of In loading(In_(0.5)Ni@SiO_(2))shows the best balance of carbon deposition resistance and DRM reactivity even after 430 h long term stability test.The boosted carbon resistance can be ascribed to the confinement of core–shell structure and to the transfer of electrons from Indium to Nickel in In-Ni intermetallic alloys due to the smaller electronegativity of In.Both the silica shell and the increase of electron cloud density on metallic Ni can weaken the ability of Ni to activate C–H bond and decrease the deep cracking process of methane.The reaction over the confined InNi intermetallic alloy nanocatalyst was conformed to the Langmuir-Hinshelwood(L-H)mechanism revealed by in situ diffuse reflectance infrared Fourier transform spectroscopy(in-situ DRIFTS).This work provides a guidance to design high performance coking resistance catalysts for methane dry reforming to efficiently utilize these two main greenhouse gases.Wenming Liu Le Li Sixue Lin Yiwei Luo Zhenghong Bao Yiru Mao Kongzhai Li Daishe Wu Honggen Peng 2022Journal of Energy Chemistry2022,31,2:3
19Numerical investigation on the flow structures in a narrow confined channel with staggered jet array arrangement显示文摘A series of numerical analyses have been performed to investigate the flow structures in a narrow confined channel with 12 staggered circular impingement holes and one bigger exit hole. The flow enters the channel through the impingement holes and exits through the far end outlet. The flow fields corresponding to two jet Reynolds numbers(25000 and 65000) and three channel configurations with different ratios of the channel height to the impingement hole diameter(Zr= 1,3, 5) are analyzed by solving the Reynolds averaged Navier–Stokes equations with the realizable k–e turbulence model. Detailed flow field information including the secondary flow, the interaction between the jets and the cross flow, and flow distribution along the channel has been obtained.Comparisons between the numerical and experimental results of the flow fields at the four planes along the channel are performed to validate the numerical method. The calculated impingement pattern, high velocity flow distribution, low velocity separation region and vortices are in good agreement with the experimental data, implying the validity and effectiveness of the employed numerical approach for analyzing relevant flow field.Liu Haiyong Liu Cunliang Wu Wenming 2015Chinese Journal of Aeronautics2015,28,6:3
