| 摘 要： | 以船体阻力性能为优化对象,基于改造母型船法,分析船艉线型的改变对船舶阻力性能的影响。根据船舶主要参数设计要求,参考同类船型,利用Tribon-Lines模块对船舶艉部型线进行改造,生成两种方案船型,并通过CFX软件对母船型以及方案船型进行粘性绕流场的数值模拟,讨论不同航速下艉部线型对船体总阻力的影响。研究结果表明,在以船体阻力性能为优化对象时,选优后的方形艉在相同的航速下阻力低、消耗的功率小、形状效应小、粘压阻力和摩擦阻力也相对较小。

| Abstract: | Taking hull resistance performance as line optimization object,the effect on performance of the hull resistance was studied based on the method of transformation original hull.Tribon-Lines module was used to transform ship stern lines with the invariable main parameters of original hull,making reference congener ship stern and generating two kinds of hull.The viscous flow of the original ship hull and the modified ship hulls was simulated numerically by CFX software to discuss the effect of stern line on th... |
