摘要
主要借助Fluent软件,采用计算流体力学方法研究消声器的空气动力学问题,重点阐述消声器的压力场和速度场,以及消声器基本结构和入口空气流速对其压力损失的影响,并提出影响声学性能的几个方面,为消声器的计算机辅助设计提供帮助。
Fluent is used to simulate the flow distribution in muffler,the air dynamics of the muffler is researched by computational fluid dynamics.Pressure and velocity distribution,as well as the effect on the pressure loss from the basical structure of the muffler and the air flow velocity of the inlet are expounded.Some factors about effecting acoustics performance is provided,which offer help for the muffler design by computer.
