Edge-flames
A previously described one-dimensional model of edge-flames is here applied to a number of new situations. These include: a description of unbounded edge-flames, for unit Lewis numbers, over the entire range of Damköhler numbers; a description of unbounded edge-flames when one of the Lewis numbers differs from unity, for which it is shown that propagating edge-flames of stationary structure may not exist; and an analysis of an edge-flame near a wall, without flow between the wall and the flame. In the case of unbounded edge-flames, a simple formula for the edge speed is derived that may be of value in the computation of turbulent combustion fields in the laminar flamelet regime.
