为了提高发动机循环性能，以某发动机设计参数为基础，以R22、乙烷及乙醇3种介质为对象，进行了第三流体循环发动机性能分析。在性能分析过程中，耦合了系统参数平衡计算与身部传热流阻仿真计算结果，力求使分析结果更接近实际情况。分析结果表明，第三流体循环与传统方式相比，可以提供更高的燃烧室压力，其中采用乙烷为循环介质的第三流体循环发动机性能最高。

In order to improve the circle performance of engines, according to the design parame- ters of some engines, the performance of third fluid circle engine is analyzed, for which R22, ethane, ethanol, helium are chosen as the mediums. During the analysis, the balance calculation result of sys- tem parameters and simulation result of flow resistance were coupled to make the analysis result clos- er to the fact. The result shows that in comparison with conventional modes, the third fluid circle can offer higher chamber pressure, and the third fluid circle engine which chooses ethane as its circle medium has the best performance.
