Abstract
Transient OH maxima were observed in the shock‐initiated combustion of rich (H2:O2:Ar = 10:1:89) hydrogen‐oxygen‐argon mixtures. Computer simulations of the reaction profiles were used to compare an assumed mechanism and set of rate constants with the experimental results. The expression k3 = 5.2×1013 exp(−27 kJ/RT) cm3 mol−1 · s−1 was derived for the reaction OH + H2 = H2O + H over the temperature range 1350–1600 K. The expression k3 = 107.50T1.77 exp(−12.7 kJ/RT) cm3 mol−1 · s−1 was derived combining our results with those of previous investigations spanning the temperature range 300–1800 K.
