Abstract

This paper presents results from part of a collaborative study carried out by Lloyd's Register (LR) and Samsung Heavy Industries (SHI) on impact analysis using Computational Fluid Dynamics (CFD). Predictions of pressures, local and global forces are presented for a variety of 2D sections of a container ship using two CFD codes, namely OpenFOAM and Star-CCM+. In an attempt to justify the influence of hydrodynamic assumptions on dynamic response, the CFD studies are carried out independently and with differing numerical strategies in particular with regard to meshing and time-stepping. Differences in the two sets of results are discussed, and numerical results are compared against experiments.
