| Abstract: | The relationship between the resistance performance of a shipform with flat bow and cochlea-channeled stern and that of conventional shipforms is investigated. A resistance model for a shipform with flat bow and cochlea-channeled stern is presented by employing such concepts as the waterline length and equivalent shipform under moving conditions. The shipform with flat bow and cochlea-channeled stern and the corresponding equivalent conventional one having the same Fn are studied with fluid mechanics of ships. The correlation between the two shipforms is proposed and the mechanism of resistance reduction of the new shipform is discussed. The results of model tests and experiments on full-scale ship are giv-en. |
