The Formation and Disappearance of Flame Islands in Reacting Mixing Layer

Abstract

The two-dimensional reacting mixing layer is numerically simulated by the integral of unsteady, incompressible Navier-Stokes equations. The chemical reaction is based on one-step, irreversible model with fast chemical kinetics and the ‘flame sheet’ model is used to describe the location and shape of combustion front. The structure of flame and its evolution are demonstrated. We are aimed to study the processes of formation, evolution and disappearance of flame islands and the effect of diffusion on these processes.
