摘　　要：为了揭示高低温介质混合过程的流体输运特性,基于CFD软件对这一过程开展了系统的数值仿真研究,分析了高低温介质之间的流体传递特性。研究结果表明,通过调整模型,出口平均速度和平均温度上产生了极小幅度的下降,出口两相流中液态锡的体积分数则有了微弱的提高,混合器综合性能并未得到本质改善;当混合器模型的液态锡入口管道的角度逆时针旋转45°和30°时,在保持R113液体与液态锡的入口参数不变时,发生了不同程度的倒灌现象。In order to reveal the fluid transport characteristics of the mixing process of high and low temperature media,this paper conducts a systematic numerical simulation study on this process using CFD software,and analyzes the fluid transfer characteristics between high and low temperature media.The research results indicate that by adjusting the model,there is a minimal decrease in the average velocity and temperature at the outlet,and a slight increase in the volume fraction of liquid tin in the two-phase flow at the outlet.The overall performance of the mixer has also been improved.When the angle of the liquid tin inlet pipeline of the mixer model is rotated counterclockwise by 45°and 30°,different degrees of backflow occurred while keeping the inlet parameters of R113 liquid and liquid tin unchanged.
