平面弧形双开闸门流量系数影响因素分析

鉴于平面弧形双开闸门为一种具有弧形闸门和横拉门的新型闸门,其流量系数的研究尚处于起步阶段,采用物理模型方法分析了不同试验工况下平面弧形双开闸门流量系数影响因素。结果表明,当闸门开度不同时,相对淹没度与流量系数呈一定的曲线关系,且流量系数随相对淹没度的增加而降低;闸门入口处断面平均弗劳德数与流量系数呈线性关系,且此线性关系与闸门开度无关。

Analysis of Influencing Factor of Flow Coefficient of Plane Radial Double Gate

In view of the plane radial double gate as a new radial gate and horizontal sliding door gate, the study of flow coefficient is still in its infancy. Physical modeling approach is applied to analyze the influencing factor of flow coefficient under different experimental conditions. The results show that under different gate opening, the relative submergence degree and the flow coefficient is certain curve relationship, and the flow coefficient decreases with the increase of relative submergence degree; the average Froude number at the entrance section and flow coefficient is the linear relationship, and the linear relationship is unrelated to the gate opening.
