摘要
采用三维声学多普勒流速仪对弯道内丁坝附近水流的紊动特性进行了系统的试验研究,较为精确地测量了弯道内丁坝附近水流的三维时均流速和脉动强度等。根据试验数据,探讨了弯道水流及丁坝附近水流的紊动机理,分析其紊动特性,同时还对紊动强度分布特点进行了比较。
This paper presents an experimental study on the turbulence intensity flow characteristics of spur dike flow. Time-average velocity and fluctuation intensity are measured from all aspects. The turbulence characteristics of spur dike flow are analyzed. The distribution characters of turbulent intensities are compared.
