Volume of fluid (VOF); Two-stage fourth order time stepping; Generalized Riemann problem method
This paper presents a method using the volume fraction of fluid (VOF) approach to track the dynamics of free boundaries. It applies a two-stage fourth order accurate time discretization method to solve the VOF equation, aiming to provide a compact diffuse-interface algorithm for simulating multi-material problems with sharp interfaces. The numerical results demonstrate high resolution and high fidelity for interface capturing.
The fraction volume of fluid (VOF) method is a successful approach to track the dynamics of free boundaries thanks to its flexibility, efficiency and simplicity. And various efficient numerical methods have been developed to solve the associated VOF equation. This paper applies the two stage fourth order accurate time discretization in [21] for the evolution of the VOF equation, aiming to provide a compact diffuse-interface algorithm simple for implementation, in order to incorporate with CFD shock-capturing schemes for the simulation of multi-material/phase problems with sharp interfaces. As such, the algorithm is decoupled from those for fluid flows as long as the velocity of the interface is given. Numerical results demonstrate the high resolution and high-fidelity for the interface capturing.
