| Summary: | This paper is concerned with the development of an efficient
scheme for solving the finite difference Navier-Stokes and energy
equations using distributed parallel computer system. The
numerical procedure is based on SIMPLE (Semi Implicit Method
for Pressure Link Equations) developed by Spalding. The
governing equations are transformed into finite difference forms
using the control volume approach. The hybrid scheme which is
combination of the central difference and up wind scheme is used
in obtaining a profile assumption for parameter variations between
the grids points. Parallelization method used on this distributed
parallel computer system is Domain Decomposition Method
(DDM). The accuracy of the parallelization method is done by
comparing with a benchmark solution of a standardized problem
related to the two dimensional buoyancy flow in a square
enclosure. The results shown that the distributed parallel computer
system will reduced an execution time to solve the problem about
70% compared to the serial computer. |
