A method for calculating 3 D discharge flow in a centrifugal impeller is developed by means of solving the incompressible steady time averaged N S equations,the continuity equation and the k ε turbulence model equation.This method is accomplished with calculation grids generated by an algebraic transformation,and thus it can be easily applied to the design analysis of centrifugal impellers.The discharge flow of a three dimensional shrouded centrifugal compressor impeller was measured for assessing the validity of the present calculation procedure.The comparison between the experimental data and the calculation results shows that the present method can predict the mean velocities.

On the basis of thin-airfoil theory, in this paper the calculating method of unsteady fluctuating lift of an annular cascade under .periodic gusts has been given, and the effects of geometrical and aerodynamic parameters of the centrifugal compressor on unsteady fluctuation lift analyzed. Using the random pulse modulation theory, a general model for calculating harmonic and broadband noise of the centrifugal compressor, and theoretical investigation of the acoustic radiation of vaned diffuser are presented. The method presented by this paper can be used to predict the acoustic radiation power of vaned diffuser due to interaction with impeller viscous wake. The results of the calculation are in good agreement with those measured by the experiments.
