大型巡航救助船快速性研究

结合大型巡航救助船的功能需求和主尺度特点，对其快速性能进行分析。运用计算流体力学(CFD)技术对原型方案的线型进行阻力性能计算，依据计算信息，分别对首轮廓线形状、球首、呆木以及支架进行优化，得到最终方案，阻力相比原型方案有了大幅降低。将最终方案进行模型试验，模型试验结果与CFD计算吻合良好，证明了本船所采用的优化方法是可靠可用的。

Hull Form Development and Research for A Salvage Vessel

Based on functional requirement and main dimensions, analysis of speed performance is carried out for a Salvage Vessel. By using of hull line optimization software, several modifications (including stem, bulb, skeg, struts) have been carried out to investigate the difference of resistance performance between the prototype and the optimized hull lines. At the condition of design draft and design speed, it indicates that the CFD resistance results of final hull line are in satisfactorily agreement with the experiment results. The resistance performances of the final hull lines have been improved by 17% in model scale. It shows that the optimization method in this paper is effective.
