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.

Keywords
