摘要：

A previously developed explicit, multiple-grid, time-marching Navier-Stokes solution procedure has been modified and extended for the calculation of steady-state high Reynolds number turbulent flows in cascades. Particular attention has been given to the solution accuracy of this procedure as compared with boundary-layer theory and experimental data. A new compact discretization scheme has been implemented for the viscous terms which has the same finite-difference molecule as the inviscid terms of the Navier-Stokes equations. This compact operator has been found to yield accurate and stable solutions in regions of the flow where the gradients are large and the computational mesh is relatively sparse.
