Mathematical Theory of Laminar Combustion. III. Perturbations.

Abstract

Perturbations of a plane premixed flame propagating steadily along a uniform duct are considered. These may be caused by heat loss through the sides of the duct, for which conditions are steady, or by slight variations in the cross section, when a slowly varying flame results. Such unsteadiness may also be self-induced. The results, which concern quenching, stability and velocity changes as well as the behavior of an elementary burner, are remarkably sensitive to whether the Lewis number is greater or less than one.
