Applications of Numerical Simulation Method to Multistage Axial Flow Compressor Three-Dimensional Flow Field

Xuezeng Zhao [2] | Xigui Wang [2] | Yongmei Wang [2]

Abstract: . Numerical simulation method (NSM) has been developed as an important technique of computational inside fluid machinery complex blade tip clearance leakage flow. Clearance leakage and end wall boundary layer and the blade boundary layer interaction makes the tip clearance flow in showing 3D eddy current characteristics. Although the geometric size of blade tip clearance compared with the whole flow passage is very small; but it is on the blade passage nearly 20 % regional flows; the tip leakage flow will result in the reduction of the tip near the work efficiency; resulting in channel blockage and local losses increase; therefore the correct prediction of the tip leakage flow phenomenon has important significance on further improve the performance of axial flow compressor rotor and expand the stable working range of the rotor.
