Calculation of 3-D laminar flows with complex boundaries using a multigrid method
Abstract
The paper reports on the use of a multigrid method for calculating three-dimensional incompressible, laminar flows with complex geometries. The flow solver, which is briefly described, is based on a finite-volume method using nonstaggered grid arrangement and general curvilinear coordinates. Following the SIMPLE algorithm of Patankar and Spalding (1972), the discretized momentum equations are solved sequentially. The applied multigrid method is a modified full-approximation scheme, updating the variable-dependent components in the source terms on coarser grids too. For the different flow configurations, the multigrid performance is described, and the predicted results are presented.
