船舶上层建筑风阻力优化及其对风浪中功率影响的研究

Optimization of Wind Resistance of Container Ship’s Superstructure and Its Influence on Received Power in Wind

对一艘万箱集装箱船的上层建筑设计了几种形式的导流罩方案,并采用CFD方法对其减阻效果进行评估.然后对满足要求的方案进行风洞模型试验,并将数值计算结果和风洞试验数据进行对比,两者吻合较好.分析了优化后的风阻对风浪中收到功率的影响,可为后续船舶风阻力的研究提供参考.

With respect to wind resistance on non-immersed areas of a container ship,seeral forms of wind bonnets were designed,and numerical calculations were performed.Both of numerical calculation and wind tunnel test indicated similar resistance reduction.The influence of the optimization of the wind resistance on the received power in the wind and waves was analyzed,which would provide a reference for further optimization of wind resistance.
