The results reveal that the flow is mainly controlled by the inflow inertia force at lower rotating speed, and it is essentially controlled by rotating effect at higher rotating speed and by both factors at transition rotating speed.

• 研究结果表明，较低转速下，进气惯性力主要控制流场内部结构，过渡转速下，进气惯性力和旋转效应同时控制流场结构，较高转速下，旋转效应主要控制流场结构。
