Kinetic study of the effect of sub-atmospheric conditions on the laminar burning velocity of high C2H6 content natural gas mixtures
The laminar burning velocity (SL) was measured at sub-atmospheric pressure (0.84
atm) and an environmental temperature of 295 ± 2K for two high C2H6 content
fuel mixtures, 75% CH4 – 25% C2H6 (mixture M1), and 50% CH4 – 50% C2H6
(mixture M2), as well as the pure constituent fuels. The equivalence ratios for the
experiments ranged between 0.8 and 1.4. Numerical calculations predicting SL were
performed using 3 detailed reaction mechanisms, finding GRI-Mech 3.0 to achieve
the best agreement at the pressure conditions evaluated. The pre-exponential factor
