超大型集装箱船多工况点的最佳方形系数范围探索

近年来，世界对超大型集装箱船多工况点兼顾的优化设计越来越重视。文中采用传统经验公式、运用CFD手段，结合实际营运工况曲线对超大型集装箱船线型进行多工况点阻力性能计算，引入每箱每海里油耗指数J，定量评估、探索最佳CB范围，最终提出具有参考价值和推广意义的多工况技术指标拆解方法和分析流程。

On optimized block coefifcient range for ultra large container vessels under multiple operating points

In recent years, more and more attention is paid to the multi-operating-point optimization design for ultra large container vessels. By combining the traditional empirical formula with CFD tools, this paper carries out the multi-operating-point resistance evaluation of ultra large container vessels together with actual operation profile to find the optimized CB range. Finally, it puts forward the index decomposition method by the multi-operating technique and analysis flow, which has reference and promotion value.
