1基于FLOW-3D的GMAW焊熔池行为数值分析模型显示文摘基于FLOW-3D软件,建立了GMAW焊传热和熔池流场的三维瞬态数值分析模型.电弧热输入和电弧压力均采用双椭圆分布模式描述,熔滴过渡过程则通过高温液态金属的质量和动量源项表征;同时,模型还考虑了电弧等离子体切应力、电磁力、重力、浮力等作用于熔池的主要应力.利用该模型对碳钢温度场及熔池流体流动进行模拟计算.结果表明:受熔滴冲击影响,熔池始终处于周期性震荡过程中,无法真正达到准稳态;同时,该模型能够模拟飞溅等焊接成形缺陷,继而可以更为全面、合理地描述焊接物理过程,为深入理解焊接内部机制提供有力支撑.胥国祥 钱红伟 朱杰 胡庆贤 CHO Jungho SUN Jinbake 2021江苏科技大学学报(自然科学版)2021,35,1:2

9Earth rotation deceleration/acceleration due to semidiurnal oceanic/atmospheric tides:Revisited with new calculation显示文摘The global oceanic/atmospheric tides exert decelerating/accelerating secular torques on the Earth rotation. We developed new formulations to accurately calculate amounts of two kinds of secular tidal torques. After Melchior, we found that an additional factor 1+k-l = 1.216, which has been formerly neglected, must be multiplied unto the tidal torque integral. By using our refined formulations and the recent oceanic/atmospheric global tide models, we found that:(i) semidiurnal oceanic lunar/solar tides exert decelerating torques of about-4.462 × 10^(16)/-0.676 × 10^(16) Nm respectively and(ii) atmospheric S_2 tide exerts accelerating torque of 1.55 × 10^(15) Nm. Former estimates of the atmospheric S_2 tidal torque were twice as large as our estimate due to improper consideration of loading effect. We took the load Love number for atmospheric loading effect from Guo et al.(2004). For atmospheric loading of spherical harmonic degree two, the value of k′=-0.6031 is different from that for ocean loading as k′ =-0.3052,while the latter is currently used for both cases-ocean/atmospheric loading-without distinction. We discuss(i) the amount of solid Earth tidal dissipation(which has been left most uncertain) and(ii) secular changes of the dynamical state of the Earth-Moon-Sun system. Our estimate of the solid Earth tidal torque is-4.94×10^(15) Nm.Sung-Ho Na Wenbin Shen Jungho Cho Kiweon Seo Young-Hong Shin Kwan-Dong Park Kookyoun Youm Sung-Moon Yoo 2019Geodesy and Geodynamics2019,10,1:1

14Elucidating the photoluminescence-enhancement mechanism in a push-pull conjugated polymer induced by hot-electron injection from gold nanoparticles显示文摘Understanding the photophysical interactions between the components in organic-inorganic nanocomposites is a key factor for their efficient application in optoelectronic devices. In particular, the photophysical study of nanocomposites based on organic conjugated polymers is rare. We investigated the effect of surface plasmon resonance(SPR) of gold nanoparticles(Au NPs) on the photoluminescence(PL) property of a push-pull conjugated polymer(PBDB-T). We prepared the hybrid system by incorporating poly(3-hexylthiophene)-stabilized Au NPs(P3 HT-Au NPs) into PBDB-T. The enhanced and blueshifted PL was observed in the hybrid system compared to PL in a neat PBDB-T system, indicating that the P3 HT chains attached to the Au NPs suppressed charge-transfer from PBDB-T to the Au NPs and relayed the hot electrons to PBDB-T(the band-filling effect).This photophysical phenomenon limited the auto-dissociation of PBDB-T excitons. Thus, the radiative recombination of the excitons occurred more in our hybrid system than in the neat system.DONGKI LEE SE GYO HAN JUNGHO MUN KIHYUK YANG SUNG HYUK KIM JUNSUK RHO KILWON CHO DONGYEOP X.OH MUN SEOK JEONG 2021Photonics Research2021,9,2:0
