 conjugate depth
 Effect of flow aeration on the second conjugate depth
 A simple formula for calculating the length and the conjugate depths of a rectangular expanding hydraulic jump is developed. The analysis is based on the experimental results obtained for certain hydraulic structures as well as the various existing literatures on the subject. The formula after having been compared with the existed ones is verified and found in fairly good agreement with the test data obtained. 本文在分析现有成果的基础上,结合某些工程试验资料,提出了矩形扩散水跃长度和共轭水 深的简易计算公式。文中还将前人的几个公式与本文提出的公式进行对比,并以实测资料给予验 证。 矩形扩散水跃水力计算的主要内容是确定水跃长度及共轭水深。本文结合一些工程试验所取得的资料,在前人研究的基础上,提出一个简单可行的计算方法。 This paper presents a diagram for hydraulic calculation of rectangular expanding stilling basin.This diagram can be used (1)to calculate the contractional depth after the outlet structure, (2)to calculate the conjugate depths and the length of rectangular expanding hydraulic jump.

Horizontal rectangular stilling basin with constant width is conventionally used downstream of a gravity arch dam spillway, but large back flows result on both sides of the stilling basin due to the centripetal effect of the water over the arch dam spillway. As a result, random oscillating and squeezing of the hydraulic jump occur, and the energy dissipation by the hydraulic jump is... The hydraulic-jump-type stilling basin is one of the principal energy dissipators used in spillway structures and outlet works. Horizontal rectangular stilling basin with constant width is conventionally used downstream of a gravity arch dam spillway, but large back flows result on both sides of the stilling basin due to the centripetal effect of the water over the arch dam spillway. As a result, random oscillating and squeezing of the hydraulic jump occur, and the energy dissipation by the hydraulic jump is insufficient. The converging stilling basin is a very effective dissi-pator in this type of problem. However, very few systematic studies have been done on hydraulic jumps in horizontal rectangular converging stilling basins for gravity arch dam spillways.Based on theoretical analysis and experiments, this paper systematically studies the characteristics of the hydraulic jump in the horizontal rectangular converging stilling basin. From the study, the formulas for conjugate depths and the length of the jump are obtained. In addition, a method to determine the contraction angle of the stilling basin is presented. Also the related statistic characteristics of the fluctuating pressure at the bottom of the basin are obtained. 水跃消能安全可靠是泄水建筑物最主要的消能方式之一。当重力拱坝采用一般常用的等宽消能池时,由于过坝水流的向心集中会导致消能池两侧产生大回流,水跃被挤压并左右随机摆动,消能极不充分,收缩式消能池是克服此项严重缺陷的有效而又简便的设施。但迄今国内外对重力拱坝收缩式消能池中的水跃尚未进行过系统研究。本文通过理论分析和试验研究,对重力拱坝下游的矩形平底收缩式消能池中的水跃进行了系统研究并给出池中水跃共轭水深和跃长的计算公式,消能池收缩角的确定方法以及池底水流脉动压强的有关统计特性,从而为矩形平底收缩式消能池的水力计算提供了可行方法。 << 更多相关文摘
