Two- and three-dimensional numerical models of multiphase flow with solid-gas-liquid phase interaction ‘DOLPHIN-2D/3D’are newly developed in this study based on a CIP method and an extended SMAC method so that irregular mesh size grids and the dynamic motion analysis of multiple rigid bodies can be taken into account. The utility of the model developed here is confirmed by applying it to collision problems between water collapse-induced bore and two floating bodies in two-dimensional and three-dimensional multiphase flow fields. The results reveal that the model can compute multiphase flow fields with the dynamic behavior of multiple rigid bodies appropriately and is capable of reducing the computation time in comparison with the results with fine regular meshes.
