Abstract :
The LBGK method based on microcosmic model is a numerical method which can be used to solve partial differential equation and simulate fluid flow phenomena. It has these virtues such as parallel computing, easy disposal for geometry boundaries and simple arithmetic. By simulating the liquid-gas variation, this paper introduces in detail the steps of realizing Boltzmann model by calling the parallel MPI library functions, studies the parallel efficiency of Boltzmann model when we use different communication models and different region partitions.
