Effects of strain on flame sheets

This discussion represents only a broad outline of the ideas. There are a number of questions of detail, for example, concerning the radial position in the jet at which a condition like Xc Xe should be applied. A position might best be selected at which the concentration of stoichiometric surfaces is greatest this lies off the axis of symmetry, at least for low liftoff heights. At sufficiently high jet velocities, very few stoichiometric surfaces will occur anywhere with Xc Xe blowoff must occur. Thus the viewpoint is consistent qualitatively with observations.
