摘 要:考虑到3吊舱推进船舶不同尾部附体形式对船舶水动力性能的影响不同,同时3桨吸收功率具有不平衡特性,以某3吊舱推进船舶为例,从快速性、操纵性和动力定位等方面分析3吊舱推进器船舶不同尾部附体形式的影响和特点,确定适合所研究船型特点的尾部附体方案,采用计算流体动力学(CFD)方法计算附体安装角度对船舶流场和阻力性能的影响,对系柱和航行状态下3吊舱推进器的螺旋桨功率不平衡进行计算和分析,结果显示,相同转速下中间桨吸收功率更大,航行状态的功率不平衡百分数明显高于系柱状态。There are different effects on hydrodynamic performance of triple pods vessels with different stern appendages,and absorbed power of the vessels is imbalance.The effects and characteristics of different appendages of a vessel with triple pods were analyzed from views of powering,maneuvering and dynamic positioning performance.The appendages for the vessel were determined.The appendages installation angle was optimized based on ship resistance performance by CFD method.The power imbalance of triple pods under bollard and navigation conditions was calculated and analyzed,showing that the power of the centerline pod is larger at the same propeller rotation rate,and the power imbalance of navigation condition is significantly higher than that of the bollard condition.
关 键 词:三吊舱推进 尾部附体 动压分布 剩余阻力系数 功率不平衡
