摘要
[目的]船舶阻力直接影响着船舶的快速性能,对于一艘海上风电运维船,快速性能是此船舶的重要性能指标之一。因此,需要计算船舶的阻力并研究有效的阻力优化方法。[方法]基于CFD方法,建立了数值模型,对某19.1 m长的双体海上风电运维船的阻力性能进行了研究,计算并分析10 kn、13 kn、16 kn和20 kn这四个不同航速下船舶的阻力,并于此船的船尾加装压浪板作为优化方法。共设计三种不同安装角的压浪板方案。对优化前后的船舶均进行了数值模拟,对得出的计算结果进行了对比分析。[结果]研究表明,在此船船尾加装适当安装角的压浪板可以有效地改善船舶在航行时的阻力性能,降阻效果比较理想。可以改变船舶的航行姿态,减小船舶航行时的升沉量和纵倾角。[结论]可以为此船舶的阻力性能计算以及优化方法设计提供参考。
[Introduction] The ship resistance directly affects the fast performance of the ship, for an offshore wind farm service vessel,the fast performance is one of the important performance indexes. Therefore, it is necessary to calculate the ship resistance and study the effective resistance optimization method. [Method] Based on the CFD method, a numerical model was established to study the resistance performance of a 19. 1 m-long catamaran offshore wind farm service vessel, the resistance of the ship at four different speeds of 10 kn, 13 kn, 16 kn and 20 kn were calculated and analyzed, and a stern flap was installed at the stern of the ship as the optimization method. Three stern flap schemes with different installation angles were designed. The ships before and after optimization were numerically simulated, and the calculation results were compared and analyzed. [Result] The research shows that the installation of stern flap with appropriate installation angle at the stern of the ship can effectively improve the resistance performance of the ship during navigation. The resistance reduction effect is ideal. The optimization method can change the navigation attitude of the ship and reduce the heave and trim angle of the ship during navigation. [Conclusion] The research results can provide reference for the calculation of ship resistance performance and the design of optimization method.
