Optimization study of flow calculation parameters of Yexietang regulating gate
Using measured data from July to August 2022 at the Yexietang Sluice,the flow conditions were categorized into submerged orifice flow and submerged weir flow based on gate opening and upstream water head variations.Flow through the sluice was calculated using traditional hydraulic methods and dimensional analysis,with adjustments to the flow coefficient.The study determined the optimal flow calculation method and formula for the Yexietang Sluice.The analysis recommends using the traditional hydraulic formula with a corrected coefficient for weir flow conditions(when<0.65)and dimensional analysis for orifice flow conditions(when>0.65).The derived formulas can also be applied to estimate the total discharge through the sluice.
