Abstract: | Based on the published research achievements,the total pressure loss and deviation angle predicting models of a new transonic axial flow compressor are improved,and the off-design performance analysis method of the corresponding transonic axial flow compressor is developed,and the corresponding computer simulation program is built.The numerical simulations of the design and off-design performance are performed in the transonic axial flow compressor.The comparison between calculation results and test results indicates that the model and analysis methods can be applied to engineering calculation. |
