Abstract :In this study, the flow around a forced rolling two dimensional hull section with bilge keel at free surface is simulated by using RANS solver. Roll damping coefficients are calculated numerically for different bilge keel width and validated with experiments to show if RANS code can correctly predict the damping coefficients. The generated vortices around the hull and bilge keel are observed by using RANS solver to show the effect on roll damping.
