Combustion Kinetics of Reentry Vehicle Ablation Materials,

Abstract

The high temperature reactions of COF2 with both CO and H2 in excess argon were studied behind reflected shock waves. The reaction of COF2 and CO, in the temperature and total concentration ranges 2400-3000K and 1.68 - .00002 m/cc, respectively, was found to be insignificant with respect to the unimolecular dissociation of COF2. The reaction of COF2 and H2 was studied in the temperature and total pressure ranges 1900-2700K and 2-12 atmospheres, respectively, varying the COF2 and H2 concentrations from 1/2% -1% to 1/4% - 4%, respectively. An empirical relationship for the apparent rate constant of COF2 was found to be virtually independent of the H2 concentration in the range of study. The results of a combined experimental and analytical study, conducted to determine a plausible COF2 + H2 reaction mechanism, are presented. (Author)
