基于FLUENT数值计算结果帆板航速预测与最佳航线设计

VPP Calculation and design of the optimal route of sailboard basing on FLUENT numerical simulating results

利用FLUENT数值模拟风帆的空气动力性能,并与试验结果进行了对比分析;利用水池试验建立了板体水动力模型。根据最大推力原理通过风动力与水动力的平衡方程求解出各条航线上的最大船速,在此基础上运用数学极值的方法计算了最佳航线。构建了一套比较完整的流体力学的研究模式,为运动员调帆和调整板体的倾斜状态提供依据,为运动员选择正确的航线提供指导。

This paper utilized the FLUENT software to simulate numerically the aerial dynamical performance of sail-wing, and compared with the results of wind tunnel test. And then utilized the balance equation of aerial and watery dynamics to solve the maximal boat-velocity in various sail-routes according to the maximal drive-force theories,and finally calculated the optimal route by using the mathematical method of extremum. This paper established a sort of research method of the fluid mechanics, what provided some effective warrants for athletes adjusting the sail and board ,and some directs for athletes choosing the correct route.
