Edge Flames in Confined Mixing Layers

The of dynamics of an edge ame con ned in a narrow channel is studied numerically within the context of a di usive-thermal model. Fuel and oxidizer, separated upstream by a thin plate, ow through a channel with a prescribed velocity. At the tip of the plate, the fuel and oxidizer mix and, when ignited, an edge ame is sustained at some distance from the plate. The objective in this work is to determine the e ect of lateral con nement on the stando distance, the ame shape, and the ame stability. We consider a wide range of widths, allow for di erential di usion and examine the e ect heat loss to the channel wall.
