USING THE RASINTERFOAM CFD MODEL FOR WAVE TRANSFORMATION AND COASTAL MODELLING

Gerald Charles John Morgan, Jun Zang, Deborah Greaves, Andrew Heath, Chris Whitlow, John Young

Abstract


The CFD model, rasInterFoam, part of the OpenFOAM library for continuum mechanics, is used to reproduce experimental results for the propagation of monochromatic waves over a submerged bar. The model is shown to reproduce the experimental results very well on the front face and top of the bar, and give adequate results on the back face, even on extremely coarse meshes. Sensitivity analyses are presented for the model results, investigating the dependence on mesh density and discretisation scheme of the model. The modeling of the wave transformations in the model is shown to be broadly insensitive to these parameters within the ranges tested.
