  • 摘要:We describe the interface-tracking and interface-capturing techniques we developed
    in recent years for computation of flows with moving boundaries and interfaces.
    The interface-tracking techniques are based on the Deforming-Spatial-Domain/Stabilized
    Space-Time formulation, where the mesh moves to track the interface. The interfacecapturing
    techniques were developed for two-fluid flows. They are based on the stabilized
    formulation, over typically non-moving meshes, of both the flow equations and an advection
    equation. The advection equation governs the time-evolution of an interface function
    marking the interface location. We also describe some of the additional methods developed
    to increase the scope and accuracy of these two classes of techniques. Among them are
    the Enhanced-Discretization Interface-Capturing Technique (EDICT), which was developed
    to increase the accuracy in capturing the interface, and extensions and offshoots of
    the EDICT.
