Effect of Shrinkage Ratio on Hydraulic Characteristics of Asymmetric Narrow Slit Ridge
Narrow slit ridges are widely used in engineering due to their excellent energy dissipation effect and easy construction characteristics.This article conducted a study on the characteristics of the water surface pro-file of the side wall and the pressure and pulsating pressure at the centerline of the bottom plate of an asym-metric slit-type bucket through model tests on three shrinkage ratios(η= 0.2,0.25,and 0.3).The results showed that the water surface profiles of the left and right side walls of the asymmetric narrow slit ridges are different but show an upward trend.The time-averaged pressure and the root mean square of the pulsating pressure on the centerline of the narrow slit bottom plate increase along the path,reaching a peak near the exit of the narrow slot,and then decrease.The pulsating pressure on the centerline of the narrow slot bottom plate basically conforms to the standard normal distribution with no obvious.
