Abstract:

The structure of turbulent flow over the ripples in an open channel is very important for sediment entrainment and transport and it is a flow characteristic that is not completely understood at present. In this study, the flow structure over ripples was investigated experimentally. To investigate flow structure, the velocity of flow over the ripples in an open channel was measured in three dimensions using an Acoustic Doppler Velocity meter (Micro-ADV). The velocity of the flow was measured at 128 points in the flow with a sampling rate of 50 samples per second. The time averaged flow velocities in the longitudinal and vertical directions were computed prior to analysis of velocity fluctuations to find the contribution of the bursting events into Reynolds shear stress. Presented herein is a discussion of the contribution of bursting events and the Reynolds shear stress as determined in this paper.
