Numerical Simulation for Transient Flow of Automobile Engine Turbocharger

摘要：

　　In order to explore the aerodynamic noise mechanism of automobile engine turbocharger compressor,a 3-dimensional unsteady mathematical model was established for turbocharger compressor.Numerical simulation for the transient flow of the turbocharger compressor was carried out.The paper focused on the characteristics of pressure pulsation in the compressor.The simulation results show the process of pressure fluctuation excitation from blade rotation in the compressor,which provides the fluid dynamics information to study the compressor aerodynamic noise mechanism.
