Development of Non-Reflective Boundary Condition for Free-Surface Flows
J. Fürst, J. Musil
Abstract:
The article presents development of non-reflective boundary condition for free-surface flows and its implementation in the framework of volume of fluid (VOF) advection method for Navier-Stokes equations in the nite-volume CFD toolbox OpenFOAM. Derivation of the boundary condition is based on simplified 1D shallow water equations as presented in [1].
Keywords:
OpenFOAM, volume of fluid, VOF, shallow water, non-reflective, boundary condition, finite volume method
