【Abstract】 The brief development history of the numerical simulation of inside flow of fluid machinery is reviewed. and the numerical methods for non-compressible turbulence inside fluid machinery and original variable method for Navier-Srokes equations are expounded. The comparison and analysis of different turbulentmodels used for flow field of fluid machinery are pressented. Finally the study direction of the numericulsimulation of inside flow of fluid machinery is proposed.更多还原
