HF Chain Reaction Laser

Abstract

The report describes a thermally initiated F2/H2 flow tube reactor experimental program to provide clearly defined experimental results via emission spectroscopy diagnostics on vibrational population levels attained in the cw H2/F2 chain reaction for comparison with theory. Highly dilute, subsonic, near room temperature reaction conditions in the 1-10 torr pressure region have been studied which result in development of the chain over flow tube distances of about 1 meter, much larger than mixing length. An examination of the dominant kinetics was conducted via the accumulation of spectral and uv data over a range of key experimental parameters including distance from the H2 injector, x; H2 flow; F2 flow pressure; dissociator temperature, and O2 additive flow. Overtone spectra were obtained. The experimental results from the flow tube on high lying vibrational population distributions ovserved at 5 torr have been compared with predictions of the 1-D scheduled mixing analytical model in a manner which attempts to identify potential key areas of kinetic uncertainty with the chain.
