摘要
以成品油船的阻力性能为优化指标,根据船体型线图,采用CATIA及ICEM软件,建立三维模型及计算域,划分结构性网格;采用计算流体力学软件(Fluent)计算目标船在变纵倾状态和吃水下的阻力值,并与船模拖曳试验相比较,分析纵倾变化对船舶阻力性能的影响规律。结果表明:该方法可以确定船舶在不同吃水下的最优纵倾值,并为船舶的实际运营提供建议,从而提高船舶的节能减排率,为发展绿色船舶提供新方向。
The purpose of this study is to optimize the resistance performance of an oil tanker, in this paper, the threedimensional ship model, calculation basin and structural meshing were performed by using the software of CATIA and ICEM according to the lines plan of the oil tanker, computational fluid dynamics software（FLUENT） was utilized to calculate the resistance of the oil tank in various trim conditions and drafts, then we compared the results calculated by numerical simulation with the towing tank test results to analyze the influence of trim variation on ship resistance performance. It is concluded that this method can find the optimal trim value in various drafts and provide practical advice for actual operating of the real ship, and as a result, it can improve the efficiency of energy-saving and emission reduction, and provide a new direction for the development of green ship.
