Abstract

Computational simulations were conducted to examine the resistance changes acting on a high-speed planing vessel as the size of the towing tank was varied. The vessel model used was a mono-hull planing vessel. The width of the computational domain ranged from 8 meters(4 meters per half-width), the actual width of the high-speed towing tank, up to a maximum of 29.16 meters(14.58 meters per half-width). The depth was varied from the actual depth of 5.5 meters up to a maximum of 14.58 meters. When the depth was 5.5 meters, resistance increased by more than 2% as the width increased, and then converged at an increase of approximately 1.5%. This trend remained similar until the depth reached 8.5 meters. However, when the depth exceeded 11 meters, the total resistance change due to the increase in width nearly disappeared. When the width was 4 meters, the total resistance showed little change due to depth, but when the width was 6 meters, the resistance variation due to depth increased up to 2.3%, converging at depths greater than 11 meters.
