5) nappe flow
跌落水流
1.
Energy dissipation in nappe flow on stepped spillways;
台阶式溢洪道中跌落水流的消能
2.
【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。
3.
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。
6) plunging nappe
跌流水舌
1.
In order to investigate the feasibility of application of contracted jet with flaring gate pier for high arch dams, the authors conducted a series of experimental survey on the plunging nappe under different water heads over weir and different angles of outlet on the basis of the theoretical analysis about the mechanism of the jet dispersion.
结果表明,采用跌流出口时,当跌流水舌在出口断面处于急流流态时,受断面收缩形成的冲击波的影响,跌流在出口断面沿垂向不同深度的水质点出射方向发生明显的改变,水舌在纵向明显拉开,具有良好的分散特性;当跌流的出口为缓流时,跌流水舌形成类似舌形坎的水舌流态,入塘水舌成月牙形,无论在纵向还是横向均充分拉开,使入塘水舌的分散度大大增加。
