Matalon–Matkowsky–Clavin–Joulin theory

The Matalon–Matkowsky–Clavin–Joulin theory or MMCJ theory refers to a longwave hydrodynamic model of a premixed flame with a large-amplitude flame wrinkling, developed independently by Moshe Matalon & Bernard J. Matkowsky and Paul Clavin & Guy Joulin, following the pioneering study by Paul Clavin and Forman A. Williams, Pierre Pelcé and Paul Clavin and by Gregory Sivashinsky. The theory, for the first time, calculated the burning rate of the curved flame that differs from the burning rate of the planar flame due to flame stretch, associated with the flame curvature and the strain imposed on the flame by the flow field.
