Numerical Study of Wakes on Downstream Effects in Static Cascade Flow Field to Simulation of Rotor Wake

The effects of moving wakes on the compressor cascade flow are discussed in this article, which can be regarded as the flow simulation between stages of compressor cascade. The moving wakes are simulated by moving cylinder before a compressor cascade flow. Different flow situations by changing the angle of wakes direction are presented by numerical simulation. The performance of cascade influenced by cylinder wakes can be related to several parameters, such as the distance between cascades in the shaft direction, the angle of wake direction. Loss of the cascade changes along with those parameters whose optimal direction is demonstrated.
