An Improved Volume-of-Fluid (iVOF) Method for Wave Impact Type Problems

In this paper, a prediction method for wave impact type problems is presented. The method is based on the Navier-Stokes equations that describe flow of an incompressible, viscous fluid. The free surface is displaced using a Volume-of-Fluid based algorithm combined with a local height function. Results are shown of steep wave simulations where the free surface profile is compared to measurements. Furthermore, results of a simulation of green water on the deck of a moving ship are shown.
