隐形球首在豪华邮轮上的应用研究

Research on the application of invisible bulbous bow on cruise

在邮轮行业的快速发展中,近年来逐渐出现了一种新型的附带隐形球首的垂直船首。为了研究隐形球首出现的原因,本文分别建立了带有常规球首和隐形球首的船型,使用STAR-CCM+对常规球首和隐形球首的船型进行水动力计算。在此基础上,绘制了2种船型的航速-阻力曲线图,分析了2种船型的快速性。研究表明,本文建立的隐形球首船型兴波阻力更小,整体快速性表现良好,且该船型仍有一定的设计和优化空间。

With the rapid development of cruise industry,a kind of new straight-stem bow with the invisible bulbous bow appear gradually in recent years.In order to study the contact ball stem appears the reason,this paper respectively established with regular bulbous bow and straight-stem bow ship model,used STAR-CCM + to calculate hydrodynamic performance of regular bulbous bow and straight-stem bow ship,on this basis,the speed-resistance curves of two types of ship models were drawn,analyzed the speed ability of these two types of ship models,found the ship model with the invisible bulbous bow established in this paper had smaller wave-making resistance,better fast performance,and there is still space for design and optimization of this ship design.
