The wake/stator interaction has been predicted using an N-S solver, in order to obtain unsteady pressure fluctuations on blade surface and the variety of unsteady vortex. So the noise can be computed. The equations are solved using a finite volume time-integration Ni scheme. For improving the ability to simulate the turbulent flow , K-ε turbulence models are utilized for the turbulent closure. Then the numerical calculations on a turbine and an axial compressor cascades are carried out in this paper.
