摘要 In this work, a hybrid numerical flux combing AUSMD and linearized approximated solver is proposed to solve the compressible two-phase flow models. The interaction of shock and rarefaction waves, the free surface and the formation and collapse of cavitation bubbles are captured clearly no matter in the 2D and 3D cases. The proposed AUSMD scheme has been applied to gas and liquid fluids universally to capture fluid discontinuities, such as the fluid interfaces and shock waves, accurately for the Ransom’s faucet problem, air-water shock tube problems, 1D stiffened water-air shock tube and 2D shock-gas interaction problems under large ratios of pressure, density and volume of fraction without the expensive cost of tedious computer time. In addition, the proposed approach is shown to deliver a good resolution of the shock-front, rarefaction and cavitation inside the evolution of high-speed droplet impact on the wall.
