Abstract

This paper describes a model for CO2 laser heating of fuel/air mixtures (contained within a reaction cell), intended for combustion kinetics research. The model identifies a previously unknown source for the hot spots which have hindered this technique. Results indicate that it is theoretically possible to create a uniformly heated field of quiescent gases, but it does not appear to be practical.
