分流对弯道水流紊动强度影响的试验研究

The study of the test of the diversion impact on the current turbulent strength of the bend of the river

采用先进的三维超声波多普勒流速仪(ADV)对不同分流比情况下弯道水流紊动特性进行了系统的试验研究。根据试验数据,探讨了不同分流比工况下弯道水流的紊动机理,分析了其紊动特性,同时对紊动强度分布特点进行了比较。

The use of advanced three-dimensional ultrasound Doppler Velocimeter（ADV） for different split ratio under the bend of the turbulent flow characteristics of the system studied.Based on the test data,to explore the different operating conditions bend the split ratio of the turbulent flow mechanism,an analysis of its turbulent characteristics,and the characteristics of turbulent intensity distribution were compared.
