Numerical evaluation of equivalence ratio measurement using OH∗ and CH∗ chemiluminescence in premixed and non-premixed methane–air flames
CS Panoutsos, Y Hardalupas, A Taylor - Combustion and Flame, 2009 - Elsevier
This work presents results from detailed chemical kinetics calculations of electronically
excited OH (A2Σ, denoted as OH∗) and CH (A2Δ, denoted as CH∗) chemiluminescent
species in laminar premixed and non-premixed counterflow methane–air flames, at
atmospheric pressure. Eight different detailed chemistry mechanisms, with added
elementary reactions that account for the formation and destruction of the chemiluminescent
species OH∗ and CH∗, are studied. The effects of flow strain rate and equivalence ratio on …

[PDF][PDF] Numerical evaluation of equivalence ratio measurement using OH* and CH* chemiluminescence in premixed iso-octane/air flames
Y Hardalupas, CS Panoutsos, G Skevis… - Proceedings of the …, 2005 - researchgate.net
This work presents results from detailed chemical kinetics calculations of electronically
excited OH (A2Σ, denoted as OH*) and electronically excited CH (A2Δ, denoted as CH*)
chemiluminescent species in iso-octane flames. Experimental evidence indicates that the
OH*/CH* intensity ratio can be correlated to local flame equivalence ratio for reacting iso-
octane fuel vapor/air mixtures. A detailed kinetic mechanism for high temperature iso-octane
combustion in flames, incorporating a OH* and CH* reaction mechanism, has been …
