Energy dissipation in nappe flow on stepped spillways;
台阶式溢洪道中跌落水流的消能
【Result】 The phenomena of flow spring takes place at a large range of nappe flow during the overflow.
【结果】台阶式溢流坝泄水过程中,在跌落水流大部分范围内产生水流跃离现象,其垂直坝面方向的跃离高度为台阶高度的2。
Experimental studies of model show that when the base slope of spillways changes within the range of 40 degrees to 60 degrees,the water-wing nearly exists in the whole nappe flow,even continues to the transition flow.
模型试验表明:当斜坡角度为40°~60°时,水翅几乎存在于整个跌落水流范围内,甚至持续到过渡水流。
