Effect of Pressure on Two-Phase Modeling for Viscous Potential Flow

In this study, the effect of pressure on the disturbed interface for two-phase stratified regime will be discussed. It is assumed that the two phases are in potential flow condition, a pressure correction algorithm for the two-fluid model is carefully implemented to minimize its effect on numerical stability. Numerical analysis is applied using the finite difference method. Actually pressure correction scheme is employed to solve the viscous potential flow model. It is designed to increase the computational stability when the flow is near the ill-posedness condition. The viscous potential flow theory fits the only pressure experimental data for air and water well.
