摘要
文中基于Sobol′方法研究了双尾船尾型参数对阻力性能和伴流质量的敏感度.以双尾3300 m 3LPG运输船作为研究对象,基于参数化模型,确定特征参数及其变化范围.进行阻力和桨盘面伴流均匀度的CFD数值计算,构建近似模型用于敏感度分析,得到对阻力性能和桨盘面伴流均匀度影响显著的设计参数.
Based on Sobol method,the sensitivity of stern parameters of twin-stern to drag performance and wake quality was studied.Taking a twin-stern 3300m3LPG carrier as the research object,the characteristic parameters and their variation ranges were determined based on the parametric model.CFD numerical calculation of drag and wake uniformity of propeller disk was carried out,and an approximate model was constructed for sensitivity analysis,and the design parameters with significant influence on drag performance and wake uniformity of propeller disk were obtained.
