Turbulence and Reynolds stress distribution in a natural river

Dates

Publication Date

Summary

Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway are discussed in this paper. The ambient velocity and the changes of velocity due to barge traffic are being continuously measured with time at three distances from the shore on one side of the Illinois River near McEvers Island. The analysis of velocity data includes the longitudinal and lateral components of velocity, turbulence intensities u' and v', and the variation of Reynolds stress (-pUV) with time. The lateral variations of Reynolds stress distributions (-pUV) for the ambient velocity and the velocity due to the movement of barge traffic have [...]
