Governing Equations of Sold-Liquid Two phase Flow and Their Applications

Three types of models, i. e. one fluid model, two fluid model and particlefluid model, are generally applied to investigate the characteristics of two phase flows. In each model, the careful consideration on the structures of governing equations and the constitutive relations employed should be needed. Essential point to be discussed in this paper is how the effects of interactions between two phases are taken into account in these basic equations.
