A two-dimensional Navier-Stokes code on parallel PCs

A parallel computer code is developed for solving the incompressible two-dimensional Navier-Stokes and energy equations. The solution algorithm is based on a second-order finite volume space discretization and a fourth-order explicit Runge-Kutta method for time advancement. The projection method is used for computing the pressure gradient in each time step. A one-direction domain decomposition scheme and message passing are used for code parallelization. The code is run on two parallel computing platforms. One parallel platform is built from two workstations and the other is a four-processor PC. The accuracy and performance characteristics of the code are tested, rated and demonstrated.
