- Abstract
- The aerothermochemistry of premixed turbulent combustion as given by the Bray-Moss-Libby model is used to develop a Reynolds stress/flux description of a flow field consisting of constant density regions of either reactants or products and of reaction zones in which density fluctuations arise as a consequence of heat release. The third-moment terms in such a description are treated on the basis of simple physical notions, while the additional modeling required for the description of the reaction zones is based on the laminar flamelet model of reacting surfaces. Finally, conventional modeling for the constant density regions is adopted. The results is a general formulation for premixed turbulent combustion based on a particular aerothermochemical model.
