摘要
介绍了一种新的发动机性能仿真软件GT-Power,它是以一维模型计算为基础,采用有限容积法对流体进行模拟运算的软件。综述了排气消声器的几种常用的研究方法,介绍了各种方法的优点和缺点,并分析了不同参数对各种消声器消声效果的影响。
One new engine performance simulation software GT--Power, which is a kind of thermal fluid simulation software based on one- dimension CFD calculation with a limited volume method is introduced. This paper reviews four types of automobile exhaust muffler simulation methods and analyzes their advantages and disadvantages. And the effects of different parameters on various mufflers are also described.
