- The numerical modeling of multiphase flows, especially compressible flows with the presence of interface and shock waves, is a challenging topic, which is still receiving increasing attentio n, particularly in engineering applications. In this study, we have developed an accurate shock and interface capturing method using curvilinear body fitted structure grids for simulating compressible multiphase flows with shock waves. A five equation mod el proficient in capturing compressible multiphase flows with unsteady shocks without nonphysical spurious oscillations is employed. The physical systems are formulated in a hyperbolic vector form in a curvilinear coordinate system and solved using a monot onic upstream centered scheme for conservation laws (MUSCL)/Godunov type finite volume scheme. Compressive MUSCL limiters combined with the high order finite volume approach can result in a sharp interface solution. The numerical models are capable of pred icting bubble shock interactions and underwater explosion with strong shock waves.
