Abstract

The of dynamics of an edge flame confined in a narrow channel is studied numerically within the context of a diffusive-thermal model. Fuel and oxidizer, separated upstream by a thin plate, flow through a channel with a prescribed velocity. At the tip of the plate, the fuel and oxidizer mix and, when ignited, an edge flame is sustained at some distance from the plate. The objective in this work is to determine the effect of lateral confinement on the standoff distance, the flame shape, and the flame stability. We consider a wide range of widths, allow for differential diffusion and examine the effect heat loss to the channel wall.
