Hydraulic Formula and Approximate Calculation of Thickener Overflow Launder

浓缩池溢流槽的水力计算问题目前国内尚没有文献对此进行过专门的探讨,根据伯努利能量方程以及明渠恒定非均匀渐变流的理论推导了其基本水力公式,并采用四阶龙格—库塔法近似计算出了沿程不同位置的水深,据此可模拟出水面曲线,并设计合适的溢流槽断面尺寸和底面坡度。

In domestic, there hasn＇t been speciilcally discussed about hydraulic calculation of thickener overflow lannder in current literature. The basic hydraulic formulas were derived based on the theory of the Bernoulli energy equation and the steady gradually varied non-uniform flow in open channel. It also approximately calculated the depth of water in different locations along the way by using Runge-Kutta method. In such cases, the water surface profile can be simulated and appropriate section size and slope of overflow launder can be designed.
