We will present a method for predicting fluid flows with gas and liquid phases separated by moving interfaces. The momentum and continuity equations of both the gaseous and the liquid phases are coupled together. The governing equations for fluid of such large density difference ratios are solved through an artificial-compressibility based algorithm. For tracking the moving interfaces, we rely on Eulerian approach by advecting the interface or interfaces on a fixed mesh. The treatment of both the liquid and gas together is an approach that can naturally extend to the simulation of heat transfer.
