摘要
随着CFD技术的逐渐成熟,该技术已被应用于线型母型的选取和线型优化等设计流程中。依托"计算流体力学的实用化研究"项目,以17.5万dwt散货船为研究对象,应用CFD软件和优化软件来改进该船的阻力性能及伴流场。选取船体艏部三个特征参数和艉部两个特征参数作为优化变量并针对每个改型进行数值模拟,并将该船原型及艏、艉部分别优化所得线型进行模型试验,试验结果与数值研究方法的结论一致。
With the maturity of CFD technology,it has already been applied to the process of choosing prototype ship and optimizing hull lines.Supported by the ＂Study of Practical CFD＂ project,a 175K bulk carrier was chosen as the studying object and CFD Technology is applied to improve the ship＇s resistance performance and wake field.3 characteristic parameters of the bulbous bow and 2 of the bulbous stern are selected as the optimizing variables and numerical simulations are carried out for each model.Experimental and numerical simulation results of the original hull form as well as the optimized hull form are compared,and coherent results are obtained.
