| 摘 要： | 采用三维数值模拟手段,对低速大小叶片轴流压气机内的流动进行了分析。结果表明压气机内存在强烈的非定常流动;小叶片将大叶片通道分成的两个通道具有不同的流量和负荷,通道之间的负荷分配对于流动的非定常性会产生较大影响;小叶片的存在重新建立了大叶片通道内的压力平衡,起到了控制大叶片表面的流动和压力分布的效果。

| Abstract: | To investigate flow in a single-stage axial flow compressor with splitter rotor,numerical simulations were carried out by using a 3-D CFD code.The results show strong unsteady flow phenomena in the rotor passage,although the isentropic efficiency shows small change with respect to time.The analysis shows that differences of mass flow and pressure rise between the two splitter-splitted passages have significant influence on unsteady flow in the compressor stage.The presence of splitter reconstructs the balance of pressure in rotor passage,and controls the flow near rotor blade. |
