本文涉及使用基于 CFD 的优化方法对油轮船尾形状进行优化。主要重点是结合自推进模拟器的应用来最小化输出马力 (DHP)，该模拟器基于雷诺平均纳维斯托克斯 (RaNS) 方程求解器的扩展，包括通过无限叶片螺旋桨理论评估的螺旋桨效应。本文概述了所给出的数值方法，并讨论了结果如何包括识别原始船体形式和优化船体形式之间的形式和积分参数的显着差异。总之，本方法似乎成功地优化了给定油轮船尾形状以实现最小 DHP，并且本文中自动演示的修改趋势与传统油轮船体形状设计中常用的趋势非常吻合。
This paper concerns tanker stern form optimization using the CFD-based optimization method. The main focus is placed on minimization of delivered horsepower (DHP) in conjunction with application of self-propulsion simulator, which is based on extension of a Reynolds-averaged Navier-Stokes (RaNS) equation solver including propeller effects evaluated by the infinite-bladed propeller theory. The paper presents an overview of the numerical method given and discusses how the results include identification of salient differences of forms and integral parameters between for the original and optimized hull forms. In conclusion, the present method appeared to successfully optimize the given tanker stern form for minimum DHP, and the modification trends automatically demonstrated in the paper agree well with those commonly in use in traditional tanker hull form designs.
