摘要
应用Fluent软件对极区航行船舶的船体-冰山会遇水动力相互作用进行研究,通过使用滑移网格和动网格方法,对风、浪、流联合作用下船舶驶经冰山时的非定常黏性流场进行数值模拟,并针对一艘极地航行的油轮和一个正方体冰山,选取不同的船速和冰体投影面积进行数值计算,得到舷侧外板水压力分布情况,分析了船冰会遇的水动力变化规律,其结果可为进一步研究极地地区风、浪、流联合作用下船冰之间的水动力相互作用提供参考,并为极地地区航行的船舶提供了设计、建造和航行建议。
Fluent software is used to study the hydrodynamic interaction between the hull-iceberg of ships sailing in polar regions. By using slip mesh and dynamic mesh methods, the unsteady viscous flow field of a ship passing an iceberg under the combined action of wind, wave and current is numerically simulated. Different ship velocities and ice projection areas are selected for numerical calculation to obtain the water pressure distribution of the side outer plate, according to a polar tanker and a cuboid iceberg, the hydrodynamic change law of ship-ice encounter is analyzed. The results can provide reference for further study of the hydrodynamic interaction between ship and ice under the combined action of wind, wave and current in polar regions, and provide suggestions for design, construction and navigation advice for ships sailing in polar regions.
