Abstract

To study extreme hydrodynamic wave impact in offshore and coastal engineering, the VOF-based CFD simulation tool ComFLOW is being developed. In this paper we will present its turbulence modeling. In particular, a blend of a QR-model and a regularization model has been designed. The QR-model belongs to a class of modern eddy-viscosity models, where the amount of turbulent eddy viscosity is kept minimal. Also, to enhance efficieny, local grid refinement has been added. For validation, experiments have been carried out at MARIN.
