| 2 | Lattice Boltzmann simulation of a laminar square jet in cross flows显示文摘A three-dimensional, nineteen-velocity(D3Q19) Lattice Boltzmann Method(LBM) model was developed to simulate the fluid flow of a laminar square jet in cross flows based on the single relaxation time algorithm. The code was validated by the mathematic solution of the Poiseuille flow in a square channel, and was further validated with a previous well studied empirical correlation for the central trajectory of a jet in cross flows. The developed LBM model was found to be able to capture the dominant vortex, i.e. the Counter-rotating Vortex Pair(CVP) and the upright wake vortex. Results show that the incoming fluid in the cross flow channel was entrained into the leeside of the jet fluid, which contributes to the blending of the jet. That the spread width of the transverse jet decreases with the velocity ratio. A layer-organized entrainment pattern was found indicating that the incoming fluid at the lower position is firstly entrained into the leeside of the jet, and followed by the incoming fluid at the upper position. | Guoneng Li Youqu Zheng Huawen Yang Wenwen Guo Yousheng Xu | 2016 | Chinese Journal of Chemical Engineering2016，24，11： | 0 |
| 3 | Experimental Study on Soot Suppression of Acetylene Diffusion Flame by Acoustic-Excited Oscillation in Rijke-Type Burner显示文摘This work reports that the flame oscillation induced by acoustic excitation can effectively suppress soot generation in Rijke-type burners.When the acoustic frequency is close to the natural frequency of the burner system,it can produce resonance resulting in intense oscillation of the flame.The relationship between the soot suppression efficiency and the acoustic field of standing wave at different flame positions is discussed.Compared with that under self-excited oscillation,when there is external forced acoustic force introduced to the flame,oscillation combustion occurred in a lager zone in the glass tube.The fundamental cause of different soot suppression efficiency at different positions is that the standing wave acoustic field causes the particles to move at different speeds in different positions of the glass tube.The axial particle velocity difference results in the formation of acoustic vortexes and the change of the flame shape.The high particle velocity causes the air in the glass tube to turn into the turbulent condition and make the flame temperature rise.Simulation results show that the surface growth rate of soot is reduced,while the oxidation rate of soot is enhanced,which result in the soot suppression under acoustic oscillation.This study can provide some reference for the practical application of oscillate combustion in soot suppression. | ZHU Yibin GUO Hui SUO Yan'ge WU Minle YE Yanghui LI Guoneng ZHANG Zhiguo | 2024 | Journal of Thermal Science2024，33，1： | 0 |
| 4 | 高功率便携式生物质燃烧驱动温差发电机的研发显示文摘利用生物质燃烧产生电力是贫困地区解决照明、通讯和医疗等基本需求的重要方式。本文开发和测试了一种高功率便携式生物质燃烧驱动的温差发电机(biomass-combustion-powered thermoelectric generator,BCP-TEG),详细研究了其温差分布、功率负载特性和不同层级的效率,并开展了现场应用测试。研究结果发现该温差发电机在自身重量为7.6 kg的条件下可同时产生750 W的热力和23.4 W的电力,热电联供效率达到32.3%。温差发电机的发电净功率密度为2.41 W·kg^(-1),均高于所有基于闭式循环冷却的文献报道结果。此外,利用本文开发的温差发电机燃烧1 kg的木条所发出的电能可充满1个容量为6.2 A·h的3.7 V锂电池。最后,论文详细讨论了BCP-TEG研究领域存在的问题和未来可研究的方向。 | Guoneng Li Jie Ying Minbo Yi Youqu Zheng Yuanjun Tang Wenwen Guo | 2023 | Engineering2023，，5： | 0 |
