对船尾伴流场的高效评估有助于前期快速判别线型的优劣。本文以某支线集装箱船已完成优化的多款线型方案为研究对象，结合CFD软件计算的标称伴流场数据，分别采用SVA标准伴流效率、SVA改进伴流效率、Marin伴流效率、传统平均伴流效率等4种伴流效率对尾部伴流不均匀度进行量化，同时以效率值为导向，研究4种伴流效率对线型方案优劣的评判影响并进行选优。结果表明，采用SVA标准伴流效率和Marin伴流效率对线型的评判具有相同的趋势效果，其值越大，线型尾部伴流场均匀度越好；SVA标准伴流效率可作为推进效率的替代值进行收到功率的预估；SVA改进伴流效率与设计桨的敞水效率值相当；传统平均伴流效率存在明显的波动性，实用性较差。
The effective estimation of the stern wake field can help determine the superiority of ship lines properly. Researching various optimized lines of a feeder, this paper adopts four wake efficiency methods (SVA standard wake efficiency, SVA improved wake efficiency, Marin wake efficiency, and traditional average wake efficiency) to quantify the non-uniformity of the stern wake. Simultaneously, their different capabilities to estimate stern wakes are analyzed to select the optimal one. The results indicate that the values of SVA standard wake efficiency and Marin wake efficiency methods show similar variation trend when estimating different stern wakes. The larger the value, the better the uniformity of the wake field at the stern. Additionally, the result of SVA standard wake efficiency can substitute the propulsion efficiency to estimate the received power. The SVA improved wake efficiency is equivalent to the open water efficiency value of the designed propeller. The traditional average wake efficiency method has significant fluctuations and poor practicality.
