Outline of Final Research Achievements

For the purpose of the development of an amphibious bus to assist disaster recovery, fundamental studies on its performance of water resistance are carried out in the present report. As a conventional bus has an almost rectangular shape, its propulsive performance on water is much less than those of general ships. In order to improve the performance on water, (1) investigations on water resistance for 3 types of bow shape and (2) investigations on flow around wheels and their effects on water resistance are carried out by means of model experiments in a circulating water channel and CFD (Computational Fluid Dynamics) simulations. Through both investigations, valuable information has been obtained for the hull form design of amphibious bus.
