Calculation of three-dimensional turbulent flow with a finite volume multigrid method

A numerical method for the efficient calculation of three-dimensional incom pressible turbulent flow in curvilinear co-ordinates is presented. The math ematical model consists of the Reynolds averaged Navier-Stokes equations an d the k-epsilon turbulence model. The numerical method is based on the SIMP LE pressure-correction algorithm with finite volume discretization in curvi llinear co-ordinates. To accelerate the convergence of the solution method a full approximation scheme-full multigrid (FAS-FMG) method is utilized. Th e solution of the k-epsilon transport equations is embedded in the multigri d iteration. The improved convergence characteristic of the multigrid metho d is demonstrated by means of several calculations of three-dimensional flo w cases. Copyright (C) 1999 John Wiley & Sons, Ltd.
