摘要
使用GT-POWER软件计算了3种抗性消声器的压力损失,并与FLUENT软件的计算结果进行了比较以验证软件的计算精度,分析了气流流速变化对消声器压力损失的影响。使用GT-POWER软件建立了发动机和排气消声器的耦合模型,研究了消声器对发动机性能的影响。
The software GT-POWER is used to calculate the pressure losses of three types of reactive exhaust mufflers, and the results are compared to that by software FLUENT to verify the accuracy of GT-POWER with the effects of the change in gas velocity on pressure losses analyzed. Then, a coupled model for engine and exhaust muffler is built by GT-POWER, with which the effect of exhaust muffler on engine performance is studied.
