| 摘 要： | 基于基元叶栅法建立了多级轴流式压气机的计算模型。建模过程中发现,空气定压比热对压气机性能计算有较大的影响。计算表明,对于级数较多的轴流式压气机,定压比热不能取定值,否则将会造成较大的计算误差。

| Abstract: | Based on blade element methods,calculation model of multi-stage axial flow compressor is built in the paper.It is found that the results are influenced greatly by specific heat of air.For a multi-stage compressor,specific heat is not considered constant in calculating the performance of compressor.Otherwise,great error will be produced. |

| Keywords: | compressor air specific heat performance |
