“…Ohmori (1998) performs simulations of unsteady combined sway and yaw motions as per captive model testing in towing tanks using planar motion mechanisms; however, the free-surface is neglected, i.e., simulations are for the so-called double body zero Froude number problem. Beddhu et al (1998), Gentaz et al (1999), and Yeung et al (2000) perform simulations for forced motions, and Sato et al (1999) and Rhee and Stern (2001) perform simulations for motions in regular head waves. With capability for more practical geometries and conditions, coupled with continuing improvements in HPC resources, the promise of CFD-based optimization will soon be realized (Tahara et al, 2000;and Dreyer, 2002).…”

Accurate simulation of free-surface wave flows around a ship is very important for better hull-form design. In this paper, a computational fluid dynamics (CFD) code which is based on the open source libraries, OpenFOAM, was developed to predict the wave patterns around a ship. Additional anti-diffusion source term for minimizing a numerical diffusion, which was caused by convection differencing scheme, was considered in the volume-fraction transport equation. The influence of the anti-diffusion source term was tested by applying it to free-surface wave flow around the Wigley and KCS model ships. In results, the wave patterns and hull wave profiles of the Wigley and KCS model ships for various anti-diffusion coefficients showed quite close patterns. While, the band width of the water volume-fraction values between 0.1 to 0.9 at the Wigley and KCS model hull surfaces was narrowed by considering the anti-diffusion term. From the results, anti-diffusion source term decreased free-surface smearing.
