本文基于双月池钻井船,采用数值模拟的方式探索了双月池结构对船舶的航行过程中附加阻力的影响。研究结果表明,与月池增阻作用直接相关的一个参数是月池长度吃水比,该比值越大,增阻效果越明显。月池对船体摩擦阻力的影响是全局性的:月池的存在会导致船体首部、平行中体、尾端以及呆木处的摩擦阻力均减小,对前月池所在的区域影响较大;月池对剩余阻力的影响具有局部性:月池对船体剩余阻力的影响主要表现在船首、尾部以及尾封板处,月池自身受到剩余阻力相比船首尾以及尾封板处的阻力增加量要大。
This paper explores the influence of the double moonpool structure on the additional resistance during the navigation of the ship by means of numerical simulation. The results show that one of the parameters directly related to the resistance enhancement effect of the moonpool is the ratio of the length of the moonpool to the draft. The larger the ratio is, the more obvious the resistance enhancement effect is. The influence of the moonpool on the friction resistance of the hull is global : the existence of the moonpool will lead to the reduction of the friction resistance of the bow, parallel middle body, tail end and deadwood, and has a greater impact on the area where the fore-moonpool is located ; the influence of the moonpool on the residual resistance is localized : the influence of the moonpool on the residual resistance of the hull is mainly manifested in the bow, tail and stern sealing plate. The residual resistance of the moonpool itself is larger than that of the bow, tail and stern sealing plate.
