Abstract

An efficient Full Approximation Storage multigrid procedure for the solution of steady-state laminar flows is described. A finite volume approach is used to descretise the governing equations of motion; the convection terms contained therein are modelled using both hybrid differencing and a new generic high-order approximation to convective transport. Two test problems have been considered with a view to assessing the effectiveness of the multigrid procedure for different boundary conditions and flow types. Results are compared for flows at different Reynolds numbers. They are encouraging (h-independent convergence being achieved in most cases) and form a base from which to extend the method to investigate more complex flow situations.
