某客滚船主尺度变化对阻力性能的影响

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1300 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。

Influence of main dimension ratio of ROPAX on ship resistance performance

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 1300 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.
