A Computer Analysis of the Kinetics of the Reaction of Vibrationally Excited Hydrogen with Atomic Oxygen in a Flowing Afterglow Experiment.
Abstract
A concerted effort was recently undertaken to gain an understanding of vibrational energy on the rate of the process O + H2(1) to OH(+) + H between atomic oxygen and H2 in its v = 1 level to produce vibrationally excited hydroxyl radicals. The purpose of this study was to test the hypothesis that reaction between ambient O and H2(1) exhausted from the rocket engine is responsible for the intense OH(+) emission observed in field measurements on the plume of a missile burning a noncarbon-containing fuel. A flowing afterglow experiment was carried out to study the process at 300K translational temperature. The extensive computer calculations on the kinetics of the O + H2 system that were performed with the Aerospace NEST computer program and have played a vital role in the planning, data acquisition, and analysis phases of the flowing afterglow experiment are presented in this report. A detailed treatment of the kinetics of the O + H2 system is included for several limiting assumptions on the effect of reagent vibrational energy on reaction rates.
