Flame propagation, wall heat transfer, and their interaction in lean premixed gases
Simultaneous data on single event flame propagation, wall heat transfer, and their interaction were obtained for a constant volume chamber. Pressure variation, wall temperature variation, and high speed schlieren movies were recorded for the combustion of methane and air for various equivalence ratios. Flame speed and wall heat flux variation with respect to time were calculated from the data. The results indicate that there are important geometry effects on flame speed due to side wall interaction. The wall heat flux data show effects due to the location of the flame relative to the location of the heat transfer measurement. Peak heat flux values occur when the flame front passes the location of measurement. High ignition energies are found to overdrive the rate of flame propagation.
