Turbulent Premixed Combustion in a Boundary Layer

Abstract
The turbulent boundary layer arising from the injection of cold reactants into a hot product stream is studied theoretically. By treating the rate of growth of the boundary layer as a small parameter and by assuming power law variations of global features of the layer the equations of a Reynolds stress closure are reduced to similarity form. A combination of the aerothermochemical model of premixed turbulent combustion due to Bray-Moss-Libby and standard models for pressure fluctuations and dissipation results in a closed set of equations which are solved numerically. The predictions are compared with available experimental data.
