The unsteady flow field of a single stage axial transonic compressor at a design point was simulated numerically

and an in-depth analysis of rotor-stator interaction was performed.Moreover

the influences of upstream wakes and potential effects on downstream blade loading distributions were investigated extensively.The results indicate that

under stage environment

upstream wakes have obvious influences on generation

evolution and transportation of flow losses

and also on loading distributions of downstream blade.Therefore

consideration shall be given to this effect in the design of turbomachinery.
