Abstract

We highlight some of the interface-tracking and interface-capturing techniques we developed for finite element computation of flow problems with moving boundaries and interfaces. Both classes of techniques are based on stabilized formulations. The interface-tracking techniques are based on the Deforming-Spatial-Domain/Stabilized Space-Time (DSD/SST) formulation, where the mesh moves to track the interface. The interface-capturing techniques, developed primarily for free-surface and two-fluid interface flows, are formulated typically over non-moving meshes, using an advection equation in addition to the flow equations. The advection equation governs the evolution of an interface function that murks the location of the interface. We also highlight some of the methods we developed to increase the scope and, accuracy of these two classes of techniques.
