A review of flame extinction

A review is presented, primarily of work pursued by the author and his co-workers over the past five years in the area of extinction of laminar flames. Most of the emphasis is placed on diffusion flames, but some consideration is given to premixed flames. The objective has been to develop simplified descriptions of extinction involving a few chemical-kinetic parameters that can be measured readily in the laboratory. The results may be applied to extinction of fires if the turbulent flames therein are composed of collections of laminar flamelets.
