Abstract

Results from the analysis of high-speed video recordings of sediment particle motion and simultaneous flow visualizations in the near wall region of a turbulent open channel flow are presented. Analysis of the video images provided information about characteristics of particle motion and its interaction with coherent flow structures associated with the turbulent bursting process near the wall. Results indicate that such interactions, in particular those involving ejection events associated with turbulent bursting, appear to be highly efficient in causing particle entrainment.
