Chemically Reacting Turbulent Shear Layers.

Abstract

An experimental investigation of entrainment, mixing and chemical reactions in a plane shear layer has been performed using laser induced fluorescence techniques. Results indicate that the reactants mix on a molecular level and react at a composition that is nearly uniform across the width of the layer. The composition of the mixed fluid is found to be asymmetric, with an excess of high speed fluid, suggesting that entrainment into the shear layer is asymmetric. These results are at variance with predictions of models based on gradient transport and eddy diffusivity. (Author)
