The Coherent Flame Model for Turbulent Chemical Reactions

摘要: A description of the turbulent diffusion flame is proposed in which structure composed a distribution laminar elements, whose thickness small comparison with large eddies. These elements retain their identity during development; they are strained own plane by gas motion, process that not only extends surface area, but also establishes rate at element consumes reactants. Where this stretching has produced high density, area per unit volume, adjacent may consume intervening reactant, thereby annihilating both segments. This shortening mechanism which, balance process, local level density. The consumption reactant then given simply product density and reactang surface. permits rather complete separation flow structure, on one hand, other, manner treatment reactions complex chemistry minimum added labor. be determined analysis, numerical computation, experiment without significant change to model.
