摘要
本文首次运用不规则游动网格的蒙特卡罗方法求解堰闸流动问题．根据蒙特卡罗方法可以独立计算区域内任一点值的特点，提出了相应的自由表面和流量的迭代计算方法．经过多组计算表明，本文方法灵活、快速，流量系数、堰面压力分布的计算值与试验值吻合良好，为蒙特卡罗法求解有自由表面的流动问题取得了成功的经验．
In this paper the sluice and spillway flow is solved by using the Monte Carlo method with irregular random walking grids.New iteration way for free surface and discharge is presented on the basis of the characteristics of Monte Carlo method.Test calculation shows that the numerical method is successful and the computational results are in agreement with the experimental data.
