Rans Simulations of the Multiphase Flow around the Kcs Hullform

Traditionally the resistance of ships has been determined using towing tank experiments. Over the past two decades increased computational power has allowed numerical approaches to replicate and potentially start to replace towing tank experiments. This work investigates the quality of results that can be achieved using a commercial Reynolds Averaged Navier Stokes (RANS) flow solver, ANSYS CFX Version 12 (ANSYS, 2009). This work is a contribution to the Gothenburg 2010 workshop on CFD in ship hydrodynamics and compares the results from CFD based methods with model tests performed by participating towing tanks on the KRISO Container Ship (KCS).
