Wide Temperature Range Kinetics of Elementary Combustion Reactions for Army Models

Abstract

The goals of this program are to provide accurate kinetic data on isolated elementary reactions at temperatures relevant to Army combustion models, particularly for propellant combustion dark zones and also for development of halon replacements for fire retardation. Measurements have been made in high temperature photochemistry (HTP) reactors. Rate coefficient expressions over wide temperature ranges are reported for the reactions O+N2O -> O2+N2,N + N2O ->N2 + NO,O +CHF3 ->OH + CF3, H + NO + Ar -> HNO + Ar, NH + CO2 ->HNO +CO. For the first of these reactions the relation to the alternate 2NO product channel is discussed. The potential impact of the results on the continuing development of Army models is considered. A statistical method has been developed for testing the exponentiality of noisy measurements in the time domain, such as are sometimes obtained in HTP and many other types of experiments.
