航行于碎冰区船舶冰阻力与冰响应探析
Analysis on ice resistance and ice response of ships sailing in brash ice
摘要
Abstract
[Objectives]In order to explore the interaction between a hull and crushed ice,[Methods]a discrete element model is combined with Euler multiphase flow.The force of a hull under different speeds and different ice levels is calculated,and the motion response of ice during ship-ice interaction discussed. The reasons for ice resistance and movement change are explained intuitively.[Results]The ice resistance of the hull is obtained,mainly due to the friction and collision of the crushed ice and hull surface,which increases with the increase of the speed,but when the speed increases to a certain value, the crushing resistance no longer increases and even reduces the trend.[Conclusions]This provides a reference for the optimization of ship type for ice zones,as well as propeller design.关键词
