A parallel multigrid method for the prediction of incompressible flows in complex geometries is investigated with respect to the performance on workstation clusters. The parallel implementation is based on grid partitioning and follows the message passing concept, ensuring a high degree of portability. A high numerical efficiency is obtained by a nonlinear multigrid method with a pressure-correction...
In this paper three-dimensional flows with conjugated heat transfer in multi-fluid and multi-channel compact heat exchangers are investigated. The underlying numerical solution method for the three-dimensional steady and unsteady incompressible Navier-Stokes and energy equations is presented, which combines efficient numerical techniques and parallel computing. The method is based on blockstructured...
Advances in parallel-vector computers have resulted in a computer architecture that is able to provide the computer power needed for large-scale flow predictions. This is demonstrated in the present paper by applying two parallel-vector computers, one with shared memory and the other with distributed memory, to the computation of stirred vessel flows for a wide range of Reynolds numbers, including...
