Notes:
This paper describes the implementation of a 3D Navier-Stokes solver within the framework of a multigrid strategy. The ability of multigrid to improve and sustain code performance over a range of mesh sizes and a variety of difficult flow problems is investigated. The code is applied to the study of the shock-induced boundary layer separation on a channel hump, the flow in a 2D cascade of compressor blades, the secondary flow development in a linear cascade of gas turbine blades and the Eckardt backswept centrifugal impeller. In each case multigrid leads to significantly improved performance.
