本文借助STAR-CCM+软件对考虑浅水效应的智能技术试验船回转操纵性进行数值模拟研究。首先对无界流场中智能技术试验船的流体动力性能评估,并且与试验结果对比验证了计算方法的准确性;在此基础上,通过改变智能技术试验船与池底的垂向距离,模拟不同浅水工况下智能技术试验船回转操纵性能。数值模拟结果表明,浅水效应下智能技术试验船侧向力系数显著增大,对应的偏航力矩系数亦有所增加。相关结论可为智能技术试验船浅水航行时安全性能提供指导。
In this paper, with the help of STAR-CCM±, the turning maneuverability of intelligent ship considering the shallow water effect is numerically investigated. Firstly, the hydrodynamic performance of the intelligent ship in the unbounded flow is numerically solved, and the accuracy of numerical method is validated with the experimental results. On that basis, by changing the vertical distance between the ship and the ground wall, the shallow effect on turning maneuverability of intelligent ship is studied. The simulation results show that both the lateral force coefficient and the rolling moment coefficient present sharp increase with the decrease of the ground distance. Relevant conclusions gotten in this article can provide some guidance for the safe sailing of intelligent ship in shallow water domain.
