为了模拟无约束状态下自由运动冰块对螺旋桨水动力性能的影响,文章使用重叠网格方法建立了冰桨相互作用的非接触模型.计算中采用六面体网格对计算域进行网格划分,然后使用动态流体-固体相互作用方法来模拟螺旋桨抽吸作用下的冰块的运动,经与冰桨作用下冰块运动轨迹实验结果的比对,证实文章方法的准确性.通过对不同大小的冰块、冰块的初始径向位置、初始轴向位置等参数变化下的螺旋桨水动力性能计算结果分析,得知:运动的冰块后方会出现一定的加速区和阻塞区.冰块大小会直接影响螺旋桨水动力性能,大尺寸的冰块在接近螺旋桨时阻塞效应比小尺度冰块更大,对螺旋桨的水动力性能影响更显著.

In order to simulate the effect of free-moving ice on the hydrodynamic performance of the propeller, a non-contact model of ice-impeller interaction was established by using the overlapping grid method. In the calculation process, the hexahedral mesh was used to conduct mesh division of the computational domain, and the dynamic fluid body interaction (DFBI) method was used to simulate the motion of ice blocks under the propeller suction effect. The accuracy of the numerical method is verified by the experimental study on the action of the ice under the influence of the ice propeller. On this basis, the influences of different parameters such as ice size, the initial radial position of ice, and the initial axial position on the hydrodynamic performance of the propeller are obtained. The results show that there are a certain accelerating area and a certain blocking area behind the moving ice block. The size of ice block has a direct influence on the hydrodynamic performance of the propeller.
