Abstract

The dynamics of an edge-flame in a mixing layer is considered. Two co-flowing streams, one of fuel and the other of oxidizer, are separated upstream by a semi-infinite plate. Beyond the tip of the plate the fuel and oxidizer interdiffuse thereby generating a mixing layer that grows downstream. A gas-phase oxidation chemical reaction takes place in the mixing layer. The flame shape consists of an edge standing at some distance from the tip of the plate and a diffusion flame trailing behind. Within the context of a diffusive-thermal model, we describe numerically the steady and unsteady behavior of the flame. Our objective is to systematically identify the conditions for the onset of oscillations examining, in particular, the influence of differential and preferential diffusion, mixture strength, flow rate and radiative heat losses.
