摘要
为研究双体船结构航行阻力,首先建立其几何模型,并将其简化为一二维流场,将流体力学理论与湍流能量耗散方程相耦合,对船身航行阻力进行流体动力学计算,得到其航行阻力特性参数。计算结果表明:本文采用的方法收敛速度较快,稳定性较好,能够有效计算船舶航行阻力,可为船舶结构设计提供参考。
In order to study the sailing resistance of a double hull ship,the geometric model is first established and is simplified as a two-dimensional flow field problem. Then the coupled fluid mechanics theory and the turbulent energy dissipation equation has carried on the fluid dynamics to ship sailing resistance calculation,and obtained the sailing resistance characteristic. Calculation results show that: the method proposed here convergence faster with better stability and can effectively calculate the ship sailing resistance. This method can provide a reference for ship structure design.
