| Abstract: | The inner unsteady flow characteristics of impeller machine act an important influence on its performance. With an increasing understanding on inner unsteady flow, to investigate its character and physical hypostasis becomes very important. This paper presents an experimental investigation method on regular shedding vortex in two dimensional compressor cascade wake and the influence on excitation. |
