On the Thermochemistry of Premixed Turbulent Combustion in Variable Enthalpy Systems

Abstract
In some turbulent flows involving premixed turbulent combustion either heat transfer or nonuniformity of the mixture leads to variations of the enthalpy. Here we extend the Bray-Moss model for the thermochemistry of such combustion to include nonisenthalpic flows. Applications are identified to boundary layers with reactants injected through a porous surface involving heat transfer, to channel flows with product streams serving as flameholders and to open flames discharging into quiescent air
