PARALLEL COMPUTATION AND ANALYSIS OF THE FLOW IN A STATIC MIXER

The use of a high-performance parallel computer system has been invest igated to compute the incompressible flow and mixing efficiency of a s tatic mixer. The flow computation is performed using a conventional Eu lerian approach, by resolving the governing flow equations on a block- structured computational mesh. To examine the mixing process, a Lagran gian approach involving particle tracking is employed. The paralleliza tion of both the flow computation and particle tracking phases of the numerical simulation, which are performed independently, is described. It is shown that a highperformance parallel computer system provides the possibility for more detailed and accurate simulations, leading to greater insights into the flow behaviour and mixing properties.
