针对碎冰条件下船-冰-水耦合阻力与碰撞的预报问题,基于CFD-DEM双向耦合模型对某冰区船舶在碎冰区的航行特性进行数值分析。数值模型中,首先基于CFD-DEM组合模型对典型的KCS船在浮冰区的阻力试验进行验证。其次,对某冰区船舶在碎冰区内的航行过程进行数值模拟,研究船舶在碎冰区航行的船-冰-水耦合阻力和兴波特性。本文的结论对碎冰条件下船-冰-水耦合阻力与碰撞的研究有一定指导意义。
The direct navigation characteristics of a ship in an ice area are numerically analyzed by using the CFD-DEM method. In the numerical model, CFD method is used to calculate the ship resistance, DEM method is used to simulate ice breaking. The resistance of KCS ship in floating ice area is verified to prove the reliability of the numerical method. The resistance and wave characteristics of a ice-going ship are analyzed. The conclusions of this paper have certain guiding significance for the study of ship-ice-water coupling resistance and collision under the condition of crushed ice.
