摘要
通过水力学试验,对于水舌撞击尾水形成的溅水分布进行研究,并运用随机溅水数值模型进行计算验证。研究结果表明,下游溅水区在水舌风的拖曳作用下,在平面上呈三角形分布,而降雨强度的纵向分布则符合伽玛函数形式。运用随机溅水模型得到的降雨强度分布与试验数据甚为吻合,证明该数值方法可以较好地模拟溅水雾化现象,具有较好的应用前景。
The rainfall distribution caused by the nappe impingement was studied in the hydraulic experiment combined with the stochastic splash numerical model. The researches show that the splash region appears as a triangle shape by the action of nappe wind. The gamma function is fit for depicting the longitudinal distribution of splash intensity. The calculated results reasonably agree with the experimental data, so it proved that the numerical method can simulate well the splash phenomena and has an optimistic foreground.
