Description

<p>This study deals with the applicability of the multiphase computational method (MICS), which enables us to calculate incompressible and immiscible gas-liquid phases including rigid solid bodies modeled by the discrete element method (DEM). To confirm the validity of the computational method, it is applied to the dam-break flows including multiple particles through a porous media structure consisting of circular objects fixed in the space. The structure is modeled by arranging particles in a line with a constant gap between the adjacent objects. It is shown that the calculated results of fluid flows without particles are in good agreement with experimental results. In addition, it is demonstrated that the movable particles in the flows are trapped by the porous structure and that the behaviors of fluids and transported particles are reasonably calculated in the cases of inviscid and viscous liquids in the computations.</p>
