Numerical Methods for a One-Dimensional Interface Separating Compressible and Incompressible FlowsStokes fluid. The gas is a compressible, multi-species, chemically reactive Navier-Stokes fluid (Fedkiw ., 1996; Fedkiw, 1996). The interface is followed with a marker particle, although the level set method will be used for the eventual 2D extension (Sussman, 1995). Away from the interface, we solv

On Some Outstanding Issues in CFD (1996)d physically complex flows, the notion of reliable, cost-effective, widely applicable and easy-to-use CFD still appears more as fiction than reality. The present monograph addresses some major areas where progress is urgently required. These areas are listed in the order a typical CFD run proceeds:

Accurate and Robust Methods for Variable Density Incompressible Flows with Discontinuitiesmight be caused by temperature effects, whereas abrupt variations are present at immiscible fluid interfaces. If interfaces are present, we wish to model their gross topological changes. The design of an incompressible flow algorithm that maintains solution accuracy and simulation robustness in the
