Duz, B. Van der Heiden, H.J.L. Van der Plas, P. Veldman, A.E.P. Faculty Mechanical, Maritime and Materials Engineering Department Marine and Transport Technology Date 2011-09-28 Abstract The simulation tool ComFLOW, developed for accurate predictions of hydrodynamic wave loading, is based on the Navier-Stokes equations. The free-surface dynamics is described through VOF, with local height-function approach to enhance accuracy. Numerical reflections are prevented by specially designed absorbing boundary conditions. Gravity-consistent density averaging for two-phase flow prevents spurious velocities near the free surface. Good progress has been made in the prediction of sloshing, green water loading and wave run-up. In the ComFLOW3 project the focus is on wave propagation, the effect of viscosity in shear layers (regularisation turbulence modelling), interactive vessel-wave dynamics and improved numerical efficiency through local grid refinement.
