The aim of this work is to describe the influence of nonuniform flow onlaminar flames. A simple steady flow analysis is presented in which gas density andmolecular transport coefficients are assumed constant and a global reaction rateexpression is employed in the high activation energy asymptotic limit. Considerablefurther simplification is achieved by a priori specification of a function related to themass flow rate normal to the flame. The analysis allows the influence of flamecurvature and strain on the mass burning rate to be clearly identified. It is shownthat, except in the weak stretch limit, the relationship between mass burning rateand flame stretch is dependent on flame geometry. Conversely the mass burning rateis uniquely related to the temperature gradient at the reaction surface irrespective offlame geometry.
