A general invariant expression is derived for the stretch experienced by a flame due either to its motion or to the nonuniform flow of the gas through it. This expression is given in terms of the local fluid velocity and the shape of the flame front. Specific examples in which the flame stretch takes a simplified form are discussed. Some remarks are made regarding the relation between the three distinct properties of flames: stretch, speed and temperature.
