基于重叠网格的豪华邮轮多工况耐波性数值分析

Multi-state luxury cruise ship seakeeping based on overlapping grids

  • 摘要:
      目的  在豪华邮轮的设计阶段,为了节约成本,需采用流体动力学(CFD)方法对设计中的邮轮进行耐波性能预报。
      方法  以一艘大型豪华邮轮为研究对象,使用自主开发的船舶水动力学CFD求解器naoe-FOAM-SJTU对模型尺度下的豪华邮轮进行耐波性数值模拟。耐波性的模拟在造波方式上采用速度入口输入式造波,对不同波高和不同浪向下的邮轮运动进行预报和总结。
      结果  评估发现,目前设计得到的邮轮船模在最大航速、波高为0.062 5,0.1和0.15 m工况下基本符合船舶舒适性要求;在设计航速下、波高为0.225 m、迎浪工况下符合船舶安全性要求。
      结论  在完成计算的工况下,邮轮的船型设计符合船舶耐波性评估标准中的安全标准和舒适性标准。

     

    Abstract:
      Objective  In the design stage of a luxury cruise ship, in order to save costs, it is necessary to use the computational fluid dynamics (CFD) method to predict the seakeeping performance of the cruise ship under design.
      Method  The research object of this paper is a large luxury cruise ship. The self-developed ship hydrodynamics CFD solver naoe-FOAM-SJTU is used to simulate the seakeeping performance of the luxury cruise ship at model scale. The seakeeping simulation adopts the speed entrance input wave-making method, and predicts and summarizes the cruise movement under different wave heights and downwards.
      Results   The evaluation finds that the designed cruise ship model basically meets the requirements of ship comfort at maximum speed and wave heights of 0.062 5, 0.1 and 0.15 m, and meets the requirements of ship safety at the design speed, wave height of 0.225 m and heading sea conditions.
      Conclusion  Under the calculated working conditions, this cruise ship design conforms to the safety and comfort standards in the seakeeping evaluation standards of luxury cruise ships.
