Publisher:Ohio State University
A new low pressure premixed gas burner flame apparatus has been constructed in our laboratory. This new facility is used to investigate the combustion of premixed gases which have relevance to the study of the combustion of energetic materials of interest to the army. The burner flame is probed in the infrared by a tunable diode laser and also by Fourier transform spectroscopy. Spatially resolved species profiles and temperatures are used as a check against theoretical models of a low pressure (20 torr) premixed methane / nitrous oxide flame. Principal species used for temperature estimation are NO and CO.
