X-FEM Simulation of Two-Phase Flows


A simulation method of transient immiscible and incompressible two-phase flows is proposed in this chapter, which demonstrates how to deal with the multi-phase flow problem by applying X-FEM methodology. In particular, the projection term consisting of discontinuity and precise integration is introduced to solve the Navier–Stokes equation. A number of numerical examples describe the interface tracking and capturing schemes used to deal with interfacial discontinuity to model incompressible two-phase flows.
