On Diffusion Flames in Turbulent Shear Flows: Modeling Reactant Consumption in a Planar Fuel Jet,

Abstract

The turbulent portion of the planar fuel jet, for isobaric subsonic flow, under fast direct one-step irreversible reaction between unpremixed fuel and oxidant, is analyzed. Mean spatial profiles for the dependent variables are found numerically and analytically from the governing nonlinear partial differential equations, based on an explicit eddy diffusion, and on a mean rate of reactant consumption proportional to the product of the mean mass fraction of fuel, the mean mass fraction of oxidant, and the appropriate local characterization of the mean rate of strain. Results from the model are qualitatively, and, in many cases, quantitatively, compatible with experimental data. (Author)
