THE VESSEL HAVING A PROTUBERANCE ON SIDE SHELL BELOW WATER LINE

摘要

PURPOSE: The vortex generator is established concentratedly in player and hull side of the vessel. The whole frictional resistance is reduced, stall can be prevented and the whole continued ratio can be improved. CONSTITUTION: A vessel having a protuberance on side shell below water line comprises the following steps. It locates at the lower part of the water plane of the outer panel surface of hull. A plurality of vortex generators(30) is established continually in the bow(10) and a hull side(20). It is composed so that the separation point in which the water stream is deviated of the vessel outer panel carried to abaft.
