摘要
随着数值计算和计算机技术的飞速发展,计算流体力学已经发展成为流体力学的主要研究手段,作为船舶优化设计和航行性能分析的基本工具,在船舶水动力学分析中得到广泛应用。该文针对船舶螺旋桨流动模拟,描述使用的网格模式和数值方法,探讨水动力计算结果对网格尺度、几何精细度表达及边界层网格形式的依赖性和敏感性,同时在数值模拟的基础上分析螺旋桨叶片边界层、梢涡和尾涡的流动特征,以及螺旋桨流场与水动力的联系。
With the rapid development of numerical technique and computer technology, computational fluid dynamics(CFD) has become the main research means of hydrodynamics. As a basic tool for ship optimization design and navigation performance analysis, CFD has been widely used in ship hydrodynamics analysis. In this paper, the mesh type and numerical method used for ship propeller flow simulation were described. The dependence and sensitivity of hydrodynamic calculation results on grid size, geometric expression precision and grid form of boundary layer were discussed. On the basis of numerical simulation, the flow characteristics of boundary layer, tip vortex and wake vortex of propeller blade and the relationship between propeller flow and hydrodynamic performance were analyzed.
