摘要
本文建议一种数值计算方法,用于研究挑射跌落水流对下游河床的冲击作用。研究表明,该方法具有计算工作量小,收敛速度快及计算精度较高的优点,并能较好地解决双自由面和上下游流量分配的问题。计算结果与实验资料吻合良好。
A numerical method is suggested to compute the flow induced by a free jet impinging op downtream riverbed. It has been shown that there are less computation work and higher rate of convergence. The shape of the free surface and the discharge ratio can also be determined. Results of computation agree well with privious experimental data.
