摘　　要：本文通过计算流体力学方法,运用Fluent软件对汽车排气系统消音器冷凝水吹出性能方面进行校核计算,与试验实测结果比较,并找出影响消音器排水性能的原因;结果表明:对排气系统消音器通过Fluent多相流计算可以准确直观的模拟出冷凝水吹出的动态流动过程,模拟结果与试验结果吻合性良好。The exhaust muffler condensate water blow-out behavior was calculated through CFD software Fluent in this paper, which was compared with test data. CFD simulation results can match the test result well, and fluent simulation can descript muffler condensate water blow-out behavior accurately, the root cause of water blow-out capability was also found.
