| 摘 要： | 介绍了一种新的发动机性能仿真软件GT-Power，它是以一维的CFD的计算为基础，采用有限容积法对热流体进行模拟计算的软件。应用该软件对发动机及消声器进行模拟和仿真，不仅能预测消声器的特性，而且还能对消声器和发动机进行有效地匹配。通过实例模型的模拟结果对比，可见该软件具有良好的预测性能。

| Abstract: | 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.Applying this software to sim ulate engines and mufflers can not only predicate characteristics of mufflers,but also carry out matching of mufflers to en gines.It is shown by comparison between the test results and the simulating results of an example model that the soft-ware has a good predictable performance. |
