摘要
为优化具有多个尺寸巨大的上层建筑物集装箱船的风阻,本文以某 20000TEU超大型集装箱船上层建筑为研究对象,开展风载荷和PIV流场测量风洞模型试验.根据得到的风阻与流场干扰特性,采用数值模拟对主体建筑纵向间距和局部构型进行优化布置,并通过风洞试验对优化结果进行验证.研究结果表明:主体建筑纵向间距是影响集装箱船风阻和甲板上方绕流场气动干扰的主要因素,合理调整上层建筑物纵向间距同时对建筑物棱角边缘倒圆角处理可以得到风阻性能更优的布置方案,经风洞试验验证,优化方案较初始方案风阻降低 47.19%,具有较大优化空间,可为超大型集装箱船总布置设计提供参考.
Abstract
Considering the superstructure of a 20000TEU ultralarge container ship as the research object,a wind tunnel model for measuring wind load and PIV flow field is tested to optimize the wind resistance of a container ship with multiple huge superstructures.On the basis of the obtained wind resistance and flow field interference,the longitudinal spacing and local configuration of the main building are optimized by numerical simulation,and the op-timization results are verified by the wind tunnel test.The results show that the longitudinal spacing of the main building is the main factor affecting the wind resistance of the container ship and the aerodynamic disturbance of the flow field around the deck.By reasonably adjusting the longitudinal spacing of the superstructure and simultaneous-ly rounding the edges and corners of the building,a layout with enhanced wind resistance performance can be ob-tained.As verified by the wind tunnel test,the optimized scheme reduces the wind resistance by 47.19%compared with the initial scheme.It also has a large optimization space that can serve as a reference for the general layout de-sign of ultralarge container ships.
