A Distributive Mass Balance Correction in Single- and Multigrid Incompressible Flow Calculation

The pressure-velocity coupling in a finite volume method (SIMPLE-type) is enhanced using a distributed mass balance correction method. The mass imbalance generated by the momentum equations is distributed over all control volumes prior to solving the pressure-correction equation. This method considerably enhances the convergence of the SIMPLE method, whether used on either a single staggered grid or a collocated multigrid. Some simple two- and three-dimensional laminar flows are used to test the method.
