| 摘 要： | 在某肥大型船母型船的基础上设计了几种球鼻艏外形方案,基于CFD技术预报了母性船桨盘面处的伴流分布,通过与试验结果的对比分析,检验了数值预报方法的适用性,在此基础上采用该方法预报了不同球鼻艏方案的桨盘面处的轴向伴流,并使用WOF方法来衡量不同球鼻艏方案对应的轴向伴流均匀情况,通过对比分析得到一种伴流分布相对较好的球鼻艏方案.

| Abstract: | This paper designs several bulbous bow geometry shapes based on one full-forrn mother ship. CFX is used to forecast the wake distribution. Through comparing with the test results, the validity of meshing method and turbulence option is tested. And the method above is used to forecast the wake distribution of each bulbous bow, and WOF method is used to measure the distribution of the wakefield. Aecording to the distribution of the wakefield, it shows a bulbous bow with better wake distribution. |
