Abstract: In this paper, a rapid convergent numerical method is proposed to solve the compressible N-S equations. This method consists of prediction, correction iteration and multi-grid steps At cascade outlet, a skill called "steady anreflecting boundary condition" is applied to accelerating the convergence of the method. The turbulent model k-ε is used.Numerical experiments were carried out at incident angle range - 13°-8°for three cascades. Comparison of turning angle and pressure distribution coefficient Cp with corresponding physical experiments are quite satisfactory.

Key words: Steady unrzflecting boundary condition skill, cascades, flow field
