Abstract:
In this study, laminar flame speeds at atmospheric pressure are
accurately measured for H2/Cl2/N2 mixtures at different equivalence
ratios and N2 mole fractions by the counterflow flame technique. A
kinetic mechanism based on recently published and evaluated rate
constants is developed to model these measured laminar flame speeds
as well as the literature data on the concentrations of H2, Cl2,
and HCl species in flat-burner flames and the ignition delay times
from shock tube experiments. The kinetic model yields satisfactory
comparison with these experimental data, and suggests that the
reactions involving excited HCl(v) species and energy branching are
not of substantial significance in combustion situations, and that
the use of accurate elementary rate constants is instead crucial to
the accuracy of the reaction mechanism.
