Abstract

This paper presents an approach for the prediction of impact loads using the open-source Computational Fluid Dynamics (CFD) code OpenFOAM. Computational results displaying the time history of impact pressures and forces for drop tests of two dimensional wedges for 20 degree and 30 degree dead rise angles and varying tilt angles are compared against experimental results from WILS JIP-III. An incompressible Volume of Fluid (VOF) computational scheme is used to capture the free surface effects. The key numerical idealisation factors of the method employed are identified and the steps taken to overcome those are described. Preliminary results using a compressible flow solver are also presented and initial investigations into the sensitivity of the results to mesh density and domain size are described.
