Abstract

We report on the experimental study of turbulent transport in the near field of swirling jets at Re = 5000 by using simultaneously the stereoscopic particle image velocimetry and planar laser-induced fluorescence methods. The present focus is on the analysis of terms of the mean (axial) momentum and scalar (mass) transport equations, estimated from the mean velocity and concentration, the Reynolds stress and turbulent flux components, measured in the central axial plane of the jets. A proper orthogonal decomposition has also been applied to the velocity data sets to analyse contribution of the coherent velocity and scalar fluctuations to the turbulent momentum and mass fluxes for different swirl rates.
