Title:
EFFECTS OF CONDUCTION AND VISCOSITY ON THE STABILITY OF LAMINAR FLAME

Abstract:
The effects of conduction and viscosity on the stability of laminar flame are examined. If L denotes the ratio of the wave length of a disturbance to the flame width and alpha is the ratio of the ultimate temperature of the burned gas to the initial temperature of the fresh mixture, the flame is found to be stable if L is less than or equal to 2 alphaalpha-1 multiplied by 1 RePr where Re is the Reynolds number of the flame based on the flame width and Pr denotes the Prandtl number of the mixture. It is further shown that the stabilization is achieved primarily through the effect of heat conduction on the flame speed rather than the influence of viscosity.
