| 摘 要： | 采用CFD软件Fluent对两种不同结构形式的双扩张腔消声器的速度场、压力场进行三维稳态流动数值模拟,研究相应的压力损失随入口流速的变化趋势.结果表明,双扩张腔消声器内部流场非常复杂,中间连通管的位置和数量对消声器内气体的压力损失有很大的影响,双连通管消声器内的压力损失比单连通管的要大.

| Abstract: | In this paper,three-dimensional steady flow numerical simulation of the velocity field and pressure field of two different forms of double cavity expansion muffler was performed by using the CFD(computational fluid dynamic method) software FLUENT,and how the pressure loss changes with the velocity of the entry was studied.Simulation results show that the internal flow field of double cavity expansion muffler is very complex;the position and number of connecting pipe has great effect on the pressure loss of ... |
