Abstract
Within the context of Eulerian approaches, we aim to develop a new interface-capturing solver to predict two-phase flow in 2D/3D Cartesian meshes. To achieve mass conservation and to capture interface topology accurately, a mass-preserving level set advection equation cast in the scalar sign-distance function is developed. The novelty of the proposed Eulerian solver lies in the introduction of a scalar speed function to rigorously reconstruct the classical level set equation. Through several benchmark problems, the proposed flow solver for solving incompressible two-phase viscous flow equations has been verified.
