2.
The turbulent jet theory and water flow momentum equation are used to establish the mathematic model for calculating bedrock scoured balance depth of river bed under the action of left-right collision of water jet from high arch dam in considering 3-D diffusion,leakage collision flow and collision energy losses of water jet dispersion in the air.
应用紊动射流理论和水流动量方程,建立了高拱坝挑流水舌左右碰撞作用下,考虑水舌空中扩散三维性、漏碰流量以及碰撞能量损失的河床基岩冲刷平衡深度的数学模型。
2) deflecting nappe
挑射水舌
1.
The arrangement is suitable to the topography of baffle areathe deflecting nappe will extend vertically and longitudinally and diffuse sufficiently with its dissipation rate increasing in the air and outer edge of nappe falling in appropria.
该布置较好地适应了消能区地形,挑射水舌沿竖向和纵向拉开、扩散较充分,水舌在 空中的消能率增大,水舌外缘落点适度,从而减轻了下游河床的冲刷,较好地解决了老炉下水库溢流坝下游的消能 防冲问题。
3) horizontal length of jet flow
水舌挑距
1.
Discussion on the horizontal length of jet flow and its factors of influence;
挑流水舌挑距及其影响因素概述
4) 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。
5) ski-jump plunge pool
