Wall heat transfer and flame propagation in a constant volume duct
Simultaneous data on single event flame propagation, wall heat transfer, and their interactions were obtained for a constant volume chamber. Pressure variation, wall temperature variation, and high speed schlieren movies were obtained for the combustion of methane and air in a constant volume duct of square cross section for a series of equivalence ratios. Flame speed and wall heat flux variation with respect to time were calculated from the data. The results seem to indicate that there are important geometry effects on flame speed due to side wall interaction. The wall heat flux data show effects due to pressure rise and due to the flame location relative to the location of the heat transfer measurement.
