Abstract
During the past decade a number of techniques have been developed which allow the study of the microstructure of flame fronts. Flame microstructure is the detailed temperature, aerodynamic, compositional history of the flame. In a one-dimensional flame where the properties vary only along a single coordinate the system can be completely described by a family of characteristic profiles which give temperature, gas velocity, stream tube area ratio, and composition as f function of a distance coordinate along the direction of flame propagation. It requires N + 1 variables to describe such a flow system together with the mass flow per unit area (i.e., the burning velocity).
