This paper presents a numerical model of multiphase flow of the mixtures of molten material-liquid-vapor, particularly in
thermal nonequilibrium. It is a two-dimensional, transient, three-fluid model in Eulerian coordinates. The equations are solved
numerically using the finite difference method that implicitly couples the rates of phase changes, momentum, and energy exchange
to determine the pressure, density, and velocity fields. To examine the model’s ability to predict an experimental data, calculations
have been performed for tests of pouring hot particles and molten material into a water pool. The predictions show good agreement
with the experimental data. It appears, however, that the interfacial heat transfer and breakup of molten material need improved
models that can be applied to such high temperature, high pressure, multiphase flow conditions. 相似文献
