Abstract

This paper addresses the hydrodynamic interaction of ship-shaped hull sections in prescribed roll motion and also in transient roll-decay motion. The flow around 2-D hull-section with four different model geometries are studied using a Finite Volume Method (FVM) based numerical model, and the results from the FVM scheme are compared with experimental data and other numerical results. For the prescribed roll motion, the effects of different hull geometries and roll angle amplitudes on the moment histories and corresponding hydrodynamic coefficients are presented, and the highest amplitude of motion studied has been increased to 20 degrees. The relation between the hydrodynamic coefficients and the corresponding roll damping rate and frequency in the case of transient roll response for different hull geometries and different initial displacements is also discussed.
