摘要: 种不同网目形状和不同网目大小的网箱模型(C1、C2、C3、C4),选取4 种不同水流流速(0.068 m/s、0.105 m/s、0.143 m/s、0.182 m/s),分别采用声学多普勒流速仪(ADV结果表明,ADV试验与PIV技术测量结果基本一致;来流速度不同时,单个网箱范围内的水流衰减程度差异不大;来流速度相同时,小网目网箱的减流效果优于大网目网箱;网目大小相同时,菱形网目网箱减流效果优于方形网目网箱

Experimental study on flow behavior at open channel confluences

《结构与土木工程前沿(英文)》 2007年 第1卷 第2期   页码 211-216 doi: 10.1007/s11709-007-0025-z

摘要: Channel confluences are common in natural rivers and hydraulic engineering, and the flow behavior at confluences becomes very complex because of the interaction between the tributary and the main river. In this study, the experiments were performed in a combined flume with a 30º angle between the main and tributary flume located at Sichuan University. The velocity was measured by using a three-component acoustic Doppler velocimeter (ADV) over a grid defined throughout the junction region. Based on the analysis of the velocity at the confluence, the distinctive characteristics of a channel confluence flow may be divided into several zones including a zone of separation immediately downstream of the junction branch channel, the maximum and minimum velocity regions at the upstream and downstream in the confluent channel, and a shear plane developed between the two combining flows downstream of the confluent channel. In addition, secondary circulations in different directions at the higher and lower velocity zones are observed as well.
