摘要: A three-dimensional incompressible viscous flow solver of the thin-layer Navier-Stokes equations was developed for unsteady turbomachinery computations. The solution algorithm flows combines dual time stepping technique with artificial compressibility approach solving governing equations. For accurate calculations, subiterations are introduced by marching in pseudo-time to fully recover continuity equation at each real step, accelerated a multi-grid
