Abstract
The paper reports additional experimental evidence supporting a new description of the mechanism of turbulent entrainment, mixing, and chemical reactions that is emerging from experiments in the last few years which reveal the presence of large scale structures in turbulent shear flows. The basic notion is that, in these flows, entrainment and mixing begin with a large scale, primarily inviscid, intertwining of the mixing species and are completed by molecular diffusion when the concentration fluctuations reach the smallest length scales that are sustained by the turbulence. Specifically, the additional evidence applies to axi-symmetric reacting turbulent jets in water, obtained using laser induced fluorescence techniques.
