Numeric Simulation of Inducer Shroud Bleeding Effect on Centrifugal Compressor Performance

In order to investigate the applied techniques that can be used to enlarge the centrifugal compressor surge-margin and to solve the problem in certain engineering design,3D viscous Computation Fluid Dynamics (CFD) code was used to simulate the inducer shroud bleeding effect on centrifugal compressor performance.Numerical experiments have been carried out to test certain design parameters involved in the application of this technique.The results show that inducer shroud bleeding has a remarkable effect on the centrifugal compressor performance improvement.
