Influence of main dimension ratio of ROPAX on ship resistance performance

    摘要
  • 摘要:
      目的  从节能减阻方面对客滚船的主尺度比进行研究。
      方法  利用模型试验和数值模拟的方法，研究船舶主尺度比（长宽比L/B、船宽吃水比B/T）变化对阻力性能的影响。
      结果  结果表明，某700客位客滚船不同L/B方案之间的有效功率在较低航速时最大差异仅为150 W，在较高航速时最大差异增大到1 300 W；不同B/T方案之间的有效功率在较低航速时最大差异为170 W，在较高航速时最大差异仅为300 W。
      结论  研究发现：增大L/B值能够明显减小实船航速对应的模型阻力和实船有效功率；不同B/T方案的实船有效功率相差不明显。

     

    Abstract:
      Objectives  This paper investigates the main dimensions of ROPAX ship in the aspect of energy saving and resistance reduction.
      Methods  By using ship model tests and numerical simulations, the effects of changes in the main dimension ratio of a ROPAX ship on its resistance performance are studied.
      Results  The results show that the maximum difference in effective power between different L/B schemes is only 150 W at lower speeds, increasing to 1 300 W at higher speeds, while the maximum difference in effective power between different B/T schemes is only 170 W at lower speeds, increasing to 300 W at higher speeds.
      Conclusions  This paper shows that increasing the L/B value can significantly reduce the model resistance and effective power of the ship, and there is no significant difference in effective power with different B/T values.
