Abstract

The commercial CFD software STAR-CCM+ is applied as a RANS solver for comparison with several potential flow codes in calculating time varying forces and moments resulting from prescribed heave and pitch motions of the ONRTH hullform. Combinations of amplitude and frequency of oscillation ranging from small to large are considered. A verification study is completed to ensure that the mesh and time step used by the RANS code are acceptable. Differences in the force and moment results from the various potential flow and RANS methods are attributed to particular code characteristics. RANS and nonlinear potential flow methods are shown to agree well for all cases considered.
