内容記述 | This paper proposes a novel method for the computation of compressible multiphase flows under the assumption of pressure equilibrium based on a 6-equation model and the AUSM (Advection Upstream Splitting Method) family. In this study, we introduce a new numerical pressure flux dissipation term based on the relative velocities in the gas and liquid phases to develop an analogous carbuncle-suppression mechanism that is applicable to gas dynamics. We also propose a mass flux dissipation term based on the pressure ratio at the gas-liquid interface and incorporate both terms into SLAU2, an AUSM-family scheme, to achieve robustness against shock anomalies. | |||||
