为探索更节能减阻的船舶编队布局，分析修长系数对船舶编队布局减阻收益的影响，运用CFD数值模拟方法对修长系数3.42～5.41范围内的单船与船队的阻力性能进行研究，取得16.46%～21.87%的船舶编队减阻收益，证明了船舶编队航行节能减阻可行，且在修长系数3.42～5.41区间内不同的船舶编队减阻收益率具有明显差异，收益率最大差值达到5.23%。通过对收益率最低的船队布局进行微调，取得最大2.5%减阻收益率的提高。分析计算结果后得出结论：船队在单列纵队布局下，修长系数不同的船型所组成的船队在航行时，船舶编队的减阻效果存在明显差异。设计船舶编队布局时，不同修长系数的船队可通过调整各船纵向间距以取得更高减阻收益。
To explore more energy-efficient and drag-reducing ship formation layouts, the impact of the slenderness ratio on the drag reduction benefits of ship formation layouts was analyzed. The resistance performance of single ships and fleets within a slenderness ratio range of 3.42 to 5.41 was studied using CFD numerical simulation methods. Results showed a drag reduction benefit of 16.46% to 21.87% for ship formations, demonstrating the feasibility of energy-saving and drag-reduction in ship formation navigation. Moreover, within the 3.42 to 5.41 range, the drag reduction benefit rate of ship formations with different slenderness ratios showed significant variation, with a maximum difference in benefit rate of up to 5.23%. By fine-tuning the layout of the formation with the lowest benefit rate, an increase of up to 2.5% in the drag reduction benefit rate was achieved. Analysis of the calculation results concluded that there are clear differences in the drag reduction effects of ship formations composed of ships with different slenderness ratios when navigating in a single-column formation. When designing ship formation layouts, fleets with different slenderness ratios can achieve higher drag reduction benefits by adjusting the longitudinal spacing between ships.
