摘要
通过制作交汇角为90°的复式断面河道“Y”型交汇河口模型,利用三维声学多普勒流速仪(ADV)和测针获取流速及水位数据,对支流河口处的水流流态包括水面形态、水流流速和水流分区进行分析。结果表明复式断面河道交汇口处流场具有很强的紊动特性,其中分离区问题是航道整治和有关环境部门应重视的部位。
By modeling of ＂Y＂-shaped junction of the compound river channel with an intersection angle 90°, the flow velocity and water level at the junction were obtained by use of the acoustic Doppler velocimeter （ADV） and point gauges. The analysis of the flow pattem at the junction, including the surface form, flow velocity, and subareas of water flow, shows that the flow field at the junction is of powerful turbulence properties, and that the problem of flow separation zone should be paid much more attention by channel regulation administration and relative environment departments.
