In this presentation, first, the high-order upwind finite difference scheme is considered for the gas-particle multi-phase shock containing flows. We used an alternative weighted essentially non oscillation scheme (AWENO) which is the numerical flux formulation of a kind of weighted compact nonlinear scheme and the use of a positive preserving limiter proposed recently which can be used with numerical flux formulation. AN AWENO scheme with a positivity preserving limiter for the density of solid particles are implemented to the gas-particle multiphase flow solver. With an AWENO scheme, we conducted 2-dimensional numerical test problem. As a result, higher resolution is obtained without blowing up of the computation by using an AWENO scheme.
