High-performance parallel computing for incompressible flow simulations

High-performance parallel computer systems have been employed to compute a variety of three-dimensional incompressible fluid flows. Three different nu merical methods have been used for the discretization of the Navier-Stokes equations, with domain decomposition techniques employed for the parallel r esolution of the discretized equations. These parallel flow solvers have be en applied to the numerical simulation of different flows, ranging from bas ic flow studies to industrial applications. The results of these studies sh ow that high-performance parallel computing has evolved from its initial in vestigative phase into a mature technology that can be employed for large-s cale numerical flow simulation.
