摘　　要：采用数值模拟方法对高粘性流体在不同夹角的分叉管合流的流动、换热进行研究,分析了不同夹角分叉管内合流的流动特性,讨论了分叉管夹角的大小对分叉管合流的流动、换热充分发展前的管道长度和压力损失的影响。The mixing flow of high viscosity fluid in bifurcation pipe with different angle was numerically simulated. The characteristic of the mixing flow was analyzed. By analyzing the calculation results, the influence of the angle of bifurcation pipe on the pipe length and the pressure loss before the mixing flow was fully developed were discussed.
