Numerical modeling of planing vessel with an interceptor

Nowadays, designers have always been interested in the use of motion stabilizer systems, such as the interceptor and trim tab, especially for planing vessels. These systems can improve crew comfort and reduce fuel consumption with favorable effects on the hydrodynamic performance of these vessels, such as reduced resistance and trim angle. In the present study, the effect of the interceptor on the hydrodynamic performance of model scaled "1/15" a monohull vessel with 11 m long that was tested in the towing tank of Sharif University of Technology compared with numerical simulation by software STAR-CCM+. The results show that the installation of the interceptor on the vessel reduces the resistance to a maximum of %9.4 when the vessel is in planing mode and in particular the dynamic trim due to the shift of the center of pressure to the transom.
