| Abstract: | By using the computational fluid dynamics(CFD) to simulate the performance of the compressor and the casing,we get their efficiency and pressure ratio characteristic curves in various speeds.After comparing this date with the experimental data,the deviation between them and the possible reasons causing of the deviation is analyzed.Then,a detailed analysis is made to the flow field of compressor,and the reasons causing the efficiency loss and the direction of optimization in the future is pointed out.Based o... |
