Parallel Fluid Flow Simulations by Means of a Lattice-Boltzmann Scheme

摘要

A parallel implementation of a lattice-Boltzmann scheme for direct numerical flow simulation is presented. Because of the locality of its operation the scheme is well suited for parallelism. Siumulations of a sample flow (the flow past a circular cylinder at Reynolds numbers between 0.3 and 120) show good agreement with experimental data reported in literature. The parallel simulations efficiently employ the computational resources, at least for computer platforms with up to eight nodes.
