A coupled volume-of-fluid and level set method in interDyMFoam solver

Abstract

InterDyMFoam is a solver for calculating immiscible two-phase flow in an open source OpenFOAM software. The solver uses the volume-of-fluid method (VOF) for capturing the fluid-fluid interface. The solver is modified to work with the coupled VOF and level set (LS) method. In the proposed method, the VOF is used to capture the interface since it is a mass conserving and the LS is used to calculate the curvature and physical quantities near the interface. A bubble rising in column liquids is used to compare the solvers. The proposed method gives an accurate calculations for the physical properties in two phase flow problems and handles the topological change of the interface.
