摘要
本文用有限元方法模拟浮体闸外部流场,将计算结果与实验对比表明:对曲线顶主闸板,水面线,压力分布及其对后铰力矩,流量系数均符合较好。计算程序方便灵活,通用性强,既可用于计算浮体闸溢流,又可用于计算常规的溢流坝溢流。
The Finite element Method, based on potential flow. isap plied to imitate Floating Gates flow. The cofficient of discharge, pressure distribution, freesurfa- -ace profile and torques of pressure are caculated for various case. The predic- -ions are compared with laboratory messurements, the agreement is found to be very good for ourvation main plate. The program is used to Floating gates and overflow dams. and is convenient.
