A 3-D viscous numerical simulation was completed for the plane cascade flow fields of end-bend and original blade with the helps of pressure-based method of N-S equations and a K-ε two equations model.In the case of using simple stagger grid

by the way of velocity modification for calculating flux of a control volume

the well-known problem of checkerboard distribution of pressure and velocity fields in the pressure-based method is well settled.The accuracy and reliability of this numerical simulation are verified with the experimental data.
