Due to concentrated suspensions for solid dispersed phase and liquid mixture, the diverse nature, so concentrated suspensions of two-phase flow system in the transport process is very complex. Two phase flow is a complex nonlinear dynamic system. In the numerical simulation movement of two-phase flow in the course of the study will be affected by many factors, so flow behavior of concentrated suspensions of two-phase flow will exhibit uncertainty and structure instability. Integrated these factors we have introduced the multi physical quantity numerical simulation software COMSOL, establishes the model to carry on the simulation research.
