Turbulence modeling, local grid refinement and absorbing boundary conditions for free-surface flow simulations in offshore applications.
To study extreme hydrodynamic wave impact in offshore and coastal engineering, the VOF-based CFD simulation tool ComFLOW is being developed. Recently, much attention has been paid to turbulence modeling, local grid refinement, wave propagation and absorbing boundary conditions. The turbulence model...
