Abstract

We describe results of numerical simulations of turbulent nonpremixed shear layers under high-strain conditions such that flame holes are formed. The novelty of the present results resides in the use of a hydrodynamic model of flame holes, where the boundary separating burning from quenched flame regions is modeled using an edge flame closure. This removes the need for detailed transport of reactive species while incorporating the effect of extinction dynamically. A parametric study to investigate the influence of the ratio of extinction scalar dissipation to mean scalar dissipation rate and the edge flame velocity to average velocity tangential to the stoichiometric surface is presented.
