摘要
介绍了一种机翼剖面形状的梯形渠道量水设施,在长春工程学院水利馆梯形渠道中通过3种不同量水槽收缩比进行了系统的组合试验,试验结果表明:该量水槽过流顺畅,水头损失较小,试验数据资料表现出很好的相关性,相关系数为R2=0.999 5。拟合的流量计算公式简明实用,计算平均误差小于1.15%,量水槽临界淹没度可达0.93。
An airfoil-shaped water-gauging facility in trapezidal channels is brought forward.Systematic experiments in trapezidal canals with 3 different contraction ratios for measuring flumes are conducted.The experimental results show that the flow through the flume is smooth,water head-loss is low,experimental data are excellent correlation,and the coefficient of correlation is R2 = 0.999 5.The fitted exponent-form flux formula is simple,the average error of the discharge calculation is 1.15%,maximum submergence extent is 0.93.
