摘　　要：以一艘阿芙拉油船为研究对象,在满足排水量和总布置要求的前提下,将船体首部原来的球艏线型改为直艏线型,并采用计算流体力学方法进行优化,以确定最终的直艏线型。将直艏优化线型与原球艏线型在3个吃水状态下的计算结果进行比较,直艏优化线型的水动力性能在这些吃水状态下均有不同程度的改善。快速性模型试验结果表明,在上述3个吃水状态下的设计航速附近,直艏优化线型的有效功率较原球艏线型均有所降低。Lines optimization for an Aframax oil tanker with vertical bow instead of the bulb bow is subjected to constraints on displacement and arrangement.In conjunction with the method of computational fluid dynamics,optimal lines are obtained finally.Computation results of optimal lines are compared with that of the original lines to verify the improvement in performance.Tests of models with bulb bow and with vertical bow are carried out separately.Results show that effective power of the optimized lines is reduced at all three tested drafts.
