摘要
参数化建模与CFD仿真技术相结合开展船舶水动力性能优化是目前船型优化走向工程实际应用的重要途经.作者以13 000 t双尾散货船为例,在CAESES软件中构建其全参数化模型,同时采用动态近似模型方法构建总阻力和伴流均匀度近似模型,将总阻力及伴流均匀度作为优化目标,利用NSGA-Ⅱ优化算法进行优化,得到Pareto解集.优化后的双尾船型在伴流均匀度降低的基础上,阻力性能得到明显改善.
Abstract
The combination of parameterized modeling and CFD simulation technology for ship hydrodynamic perform-ance optimization is an important way for ship design optimization to be applied in engineering practice.Taking a 13 000 t twin-tail bulk carrier as an example,this paper constructs its fully parameterized model in CAESES software,and the dy-namic approximation model method is employed to construct the total resistance and wake uniformity approximation mod-els.The total resistance and wake uniformity are optimized using the NSGA-Ⅱ optimization algorithm as the optimization objectives,and the Pareto solution set is obtained.The optimized twin-tail ship model shows significant improvement in re-sistance performance on the basis of reduced wake uniformity.
