Numerical study on the hydrodynamic interactions between two ships arranged side by side

摘要

3-D Rankine source method is used to investigate the hydrodynamic interactions between two ships arranged side by side with or without forward speed. A new radiation condition, which takes Doppler shift into account, is imposed on the control surface. The present method was validated through two pairs of models both in beam and head waves. Model 1 is about a modified Wigley hull and a rectangular box model at beam sea condition without speed and Model 2 is about a full scale supply ship and frigate model at head seam condition with forward speed. The method developed was validated through model experiments as well as the published numerical programs and a good agreement was obtained.
