摘　　要：本文用MicroADV对低含沙水流的紊动结构进行了较为系统的研究 ,在不同的粒径下 ,泥沙颗粒对流体流动结构的改变不一致 ;同样地 ,相同的粒径在不同的水流条件下 。The turbulent structure of sediment-laden flow at lower concentration was studied using a newly developed velocimetry-MicroADV. It was found that the different particle sizes had different influences on the flow structure and under different flow conditions, the same particle also had evidently different effects on the flow.

关 键 词：低含沙水流 紊动结构 MICROADV 两相流
