| 中文摘要: |
| 以初始抛射速度、出射角、偏移角和水滴直径等四个物理量为随机变量，建立了水滴随机碰溅的数学模型，并应用龙格 库塔(Runge Kutta)法和蒙特卡罗(Monte Carlo)法，求得挑流泄洪雾化的地面降雨强度。最后给出了一个工程实例，其雨强的计算值与原观值变化趋势基本一致。 |
| 英文摘要: |
| A mathematical model of droplet formed by impinging of nappe on plunge pool is established.Four random variables including initial ejection velocity,emergence angle,deveiation angle and droplet diameter are adopted.The rainfall intensity distribtuion is calculated by means of Runge Kutta method and Monte Carlo method.The calculation of a case study is given.It shows that the calculated distribution trend is in good agreement with the prototype observation data. |
