Abstract: Constitutive equations regarding the drift flux model for a multiphase flow consisting of molten material and its solidified particles were thermodynamically derived under a condition of local quasiequilibrium. The basic equations, including the conservation equations and the constitutive equations for the multiphase flow, were expressed in dimensionless forms. The theory developed here confirmed that the temperature fields closely depended on the Lagrangian derivative of the solid fraction accompanying the latent heat effect, and was characterized by the Stefan number. It was also suggested that the simplified basic equations corresponding to the phase equilibrium diagram were useful in the analysis of multiphase flow with solid-liquid phase change.
