3) flow passing through turbine
过机水流
4) transition flow
过渡水流
1.
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。
2.
Model experimental studies indicating 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 continuing to the transition flow.
模型试验表明:当斜坡角度为40°～60°时,水翅存在于几乎整个跌落水流范围内,甚至持续到过渡水流;随着溢洪道底坡的增大,水翅存在的流量变化范围增大、高度增加;随着台阶尺寸的减小,水翅高度降低,所存在的流量变化范围缩小。
3.
7°,19° and 30°) shows that energy dissipation ratio under skimming flow,transition flow or nappe flow,would not be confined by the relative critical water depth on weir (y_c/h≤2.
5时,滑行水流、过渡水流和跌落水流消能率的大小不受堰上相对临界水深的限制,而只是相对坝高Hdam/yc和斜坡角度的函数,即随坡度变缓或相对坝高Hdam/yc增加,消能率增大;当坝坡相同坝高相等时,滑行水流、过渡水流和跌落水流之间的消能率差异很小,并且其消能率大小与台阶个数无关;此外,文中还给出了计算消能率的经验公式。
