We shall now examine the left stability boundary that was uncovered in lecture 5 in our discussion of NEFs figure 5.3. The boundary is associated with instabilities leading to cellular flames, i.e. flames whose surfaces are broken up into distinct luminous regions cells separated by dark lines. Each line is a ridge of high curvature, convex towards the burnt gas. For a nominally flat flame these cells are very unsteady, growing and subdividing in a chaotic fashion but curvature, for example, can make stationary.
