DIAGONALLY INVERTED LOWER-UPPER FACTORED IMPLICIT MULTIGRID SCHEME FOR THE THREE-DIMENSIONAL NAVIER STOKES EQUATIONS

A diagonally inverted, lower-upper, approximately factored, implicit multigrid algorithm is developed to calculate three-dimensional compressible viscous flows. This scheme solves the full Reynolds-averaged Navier Stokes equations with a k-e model of turbulence. The flow equations are solved within the framework of the multigrid method using a four grid level W-cycle, while the k-e equations are solved only on the finest grid and uncoupled from the flow calculations. This treatment proves to be an efficient method for calculating three-dimensional compressible viscous flows.
