摘要
根据计算流体力学原理,运用FLUENT软件对圆弧形硬帆风帆进行数值模拟,对风帆动力特性进行分析,并对船舶安装风帆的节能效果进行研究.以吉达—青岛航线为例,对30万t以下油船和散货船安装风帆的节能效果进行计算分析.结果表明,大部分船舶安装风帆后可节能4%~10%.
In terms of the principle of computational fluid dynamics,the aerodynamics performance and influencing factors and the result of power saving of the circular-arc sail were analyzed by using the software of FLUENT.Taking Jeddah-Qingdao route as an illustration,the effect of energy saving on different tons of oil-carriers and bulk carriers which had installed sails were calculated.Results show that the effect of energy saving can reach 4%～10% for most of the ships installed with sails.
