Application of MUSTA Scheme for Simulation of Dilute Particle-Gas Two-Phase Flow

Abstract:

The Multi-Stage (MUSTA) scheme was used to construct the numerical fluxes when the hyperbolically degenerate governing equations, in which the independent eigenvectors can not be found, are numerically solved for dilute particle-gas two-phase flows. The abilities of MUSTA scheme used in various problems were analyzed. It was found that the MUSTA scheme is effective even for very complicated problem although appropriate total number of stages should be carefully selected. When the total number of stages equals 3 or 4, the MUSTA scheme is as accurate as Riemann solver in most cases.
