PARALLEL COMPUTATION FOR FLUID-STRUCTURE THERMAL INTERACTIONSWITH MULTIPHASE MODELING

Maruyama, K.; Toriu, D.; Ushijima, S.

Full Article:

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 phaseaveraged governing equations, including the energy equation to predict temperature distributions, 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.
