Abstract

The dynamics of an edge flame in a mixing layer is considered. The flame, which stands at a well-defined distance from the plate separating the fuel and oxidizer streams, is stabilized by heat conducted back to the relatively cold plate. It has a tribrachial structure that consists of a lean premixed segment leaning toward the oxidizer side, a rich premixed segment leaning toward the fuel side, 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. The primary objective is to systematically identify the conditions for the onset of oscillations examining, in particular, the influence of differential diffusion, mixture strength, flow rate, and radiative heat losses.
