Abstract

An idealized model for turbulent flames is introduced. It consists of a scalar advection-react ion-diffusion equation that describes the interaction of a thin flame with a turbulent-like flow field acting on two separate scales. Rigorous asymptotic results as well as affordable and reliable direct numerical simulations are available to describe the effective large scale behavior of the idealized front; a strategy is proposed to use this framework to validate closure models for more realistic turbulent flames. Examples are given to illustrate the strategy as applied to premixed flames.
