Abstract:

This experimental study explores the distribution of Reynolds shear stresses and turbulence intensities for a flume receiving lateral inflow via a set of vertical nozzles. The data set allows for developing turbulence models to describe a wider range of spatially-varied flow conditions. The turbulent flow structures are detailed both in the near-field close to where the flow enters the flume, and in the far-field. It was found that a lateral inflow increases the turbulence level, but it decreases in the transverse direction towards the side walls. As the lateral inflow rate increases, the turbulence parameters increase only slightly. The turbulence parameters also increase from the upstream end of the lateral inflow zone towards the downstream end. The turbulent kinetic energy (TKE) production was estimated. Small regions of negative TKE production exist, which are typically near the lateral inflow addition. © 2012 Copyright International Association for Hydro-Environment Engineering and Research.
