Eine Verallgemeinerung der Navier-Stokes-Gleichungen auf Zweiphasenströmungen

We derive a system of equations, related to the well-known Navier-Stokes equations and Allen-Cahn equation, describing a gas-liquid fluid. We show the consistency of the model with the 2nd law of thermodymics. Furthermore, some numerical calculations in two space dimensions are pres ented.
