摘要

门控管道涉及高速空气-水流动。在对门控管道的研究中，确定了需气比随水力参数和几何参数的变化而变化。然而，目前还没有研究水闸高水头管道断面几何形状对风量比的影响。本文研究了管道截面几何形状对风量需求比的影响。结果表明，管道截面几何形状对风量需求比有重要影响，特别是在10%和15%闸门开启率下。可以看出，管道几何形状对空气需求比的影响在20%和更大的闸门打开率时减小。在此基础上，提出了风量比与闸门开启率、弗劳德数、水力半径和管道长度的关系式，用于估算风量比。

An experimental investigation of the geometry effect on air-demand ratio in conduits with a sluice gate

Gated conduits involve high-velocity air-water flow. When the studies on the gated conduits are examined, it is determined that the air-demand ratio changed according to the hydraulic and geometric parameters. However, no study has investigated the effect of the cross-sectional geometry of high-head conduits with a sluice gate on the air-demand ratio. In this study, the effect of conduit cross-sectional geometry on the air-demand ratio is examined. Results indicate that conduit cross-sectional geometry is an important effect on the air-demand ratio, especially at 10% and 15% gate opening rates. It is seen that the effect of the conduit geometry on the air-demand ratio decreases at 20%, and greater gate opening rates. Moreover, a formula for the air-demand ratio is presented relating the air-demand ratio to the gate opening rate, Froude number, hydraulic radius, and conduit length was presented for estimating the air-demand ratio.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
