PARALLEL COMPUTATION FOR FLUID-STRUCTURE THERMAL INTERACTIONS WITHMULTIPHASE MODELING

Abstract. This paper presents a computational method to predict gas-liquid-solid multiphase phenomena. In addition to the mechanical interactions between the different phases, their thermal interactions are taken into account in the present multiphase modeling. The phase-averaged governing equations, including the energy equation to predict temperature distribu-tions, are discretized with a finite volume method and calculated with the numerically stable and accurate algorithms. The numerical procedures are parallelized with flat MPI so that it can be executed on recent large-scale distributed memory systems. It was applied to basic engineering problems and its validity was discussed
