摘要：In this talk, we present recent investigation on inflow/outflow problem for full two-phase flow, which consists of two compressible Navier-Stokes equations coupled each other through the drag force relaxation mechanisms and is derived by the Chapman-Enskog expansion from the Vlasov-Navier-Stokes for mixed fluid-particle motion. The existence of unique steady-state is shown respectively corresponding to supersonic, sonic, and subsonic flow state at far field. The nonlinear stability and long time convergence rates are also established.Meanwihle, the comparison of full two-phase flow with one phase compressible viscous equations and drift-flux two-phase flow models are made. This is joint with Shuang Zhao.
