1) aeration ramp
通气挑坎
2) aeration ridge
掺气挑坎
1.
According the experiment data,we analyzed the alternation of water surface profile which changed by the aeration ridge of flood way,from it,we knew that the aeration ridge can increase the water depth of channel,and the influence depends on flow velocity,the shape of aeration rid.
利用已有的试验资料分析了泄槽设置掺气挑坎后对水面线产生的扰动影响。
2.
The results showed that when spillway has many aeration ridges,the distributing of dynamic water pressure is abnormity.
通过对已有溢流混凝土面板堆石坝模型试验成果的分析,发现当泄槽设置多道掺气挑坎时,由于掺气挑坎对水流的扰动影响,使得泄槽底板上的动水压强分布极不规则,作用于泄槽底板上动水压力的模型试验实测值与计算值相差较大,并随底板在泄槽中所处的位置而变化;根据模型试验实测值与计算值的对比,提出了计算底板动水压力时的修正建议。
3) bucket aerator
掺气挑坎
1.
Experimental and numerical modeling for the location of a bucket aerator on an arch structure;
渥奇面上掺气挑坎位置的试验与数值计算分析
2.
When a bucket aerator is laid on an arch structure,serious spray may occur with high velocity,intense spray is negative to the discharging structure,which should be avoided.
渥奇面上设掺气挑坎,流速大时可能发生散水现象,强烈散水会对泄洪建筑物产生不利影响,应尽可能避免。
4) side contracted ramp
侧收缩掺气挑坎
1.
Basic principles for design of the aerator are described, and a new aerator, that is the side contracted ramp, is presented.
结合二滩水电站1号泄洪洞,研究了反弧段边墙掺气问题,基于掺气挑坎设计中应遵循的基本原则,提出了一种新型的斜侧收缩式掺气挑坎体形,并分析了影响侧收缩掺气挑坎挟气量及挑坎下游水流流态的因素。
5) flip bucket
挑坎
1.
The study for the flip bucket style optimization test in Longkaikou hydropower station
龙开口水电站挑坎体型优化试验研究
2.
Application and research of method of characteristics in design of flip bucket for spillway tunnel at Xiluodu Hydropower Project is mainly presented .
采用特征线法建立了异形扭曲底面条件下的泄洪洞挑坎水流流场计算数学模型并编制了可视化计算程序 ,由计算结果可以得到挑坎上水流的自由表面形态、断面水深和沿垂线平均的流速分布。
3.
The flip bucket is a expanding type o.
挑坎的原设计方案为一扩散坎,且布置在河道右岸,出射水流主要集中在右岸,不能满足下游边坡稳定和防冲要求,必须对坎型进行优化。
6) continuous flip bucket
连续挑坎
