3D COMPUTATIONAL METHOD TAKING ACCOUNT OF THERMAL INTERACTIONS BETWEEN TWO-PHASE FLUIDS AND COMPLICATED-SHAPED SOLIDS

In this study, a computational method was developed to predict thermal interactions between immiscible two fluids and complicated-shaped solid objects on the basis of the multiphase model. In our numerical method, thermal and mechanical interactions between fluids and complicated-shaped solids are predicted accurately. Phase-averaged governing equations are discretized with a finite volume method (FVM) and SMAC method is used as a numerical algorithm. The present method was applied to natural convections in two immiscible fluids and porous media with which the voids are filled by two immiscible fluids. As a result of computations, velocity and temperature distributions are reasonably predicted.
