Abstract:

Near-equidiffusional flames NEFs are characterized by near-unity Lewis numbers, near-adiabatic flame temperatures and near-uniform enthalpies. These flames are special three-dimensional solutions of the combustion equations and provide a convenient framework for the theoretical study of a number of flame phenomena. An extensive discussion of NEFs appears in Chapters 2 and 8 of Buckmaster and Ludford 1982, where a set of reduced equations governing these flames has also been derived. This paper is concerned with a study of the linearized stability problem associated with the plane NEFs.
