Abstract

A pressure-based composite grid (multiblock) capability has been developed for incompressible and compressible, and laminar and turbulent flows. Patched (abutting) grids are used, and a locally conservative flux treatment is employed at the interfaces between blocks. For computational efficiency, a Full Approximation Full Multigrid(FAS-FMG) method has also been incorporated into the solution framework. A controlled variation scheme (CVS), which uses a second-order flux estimation bounded by flux limiters, is used to discretize the convection terms. A k-ε model with wall functions, is used for modelling the effects of turbulence. Selected 2-D and 3-D results are presented which illustrate the characteristics of the overall method.
