摘要

The effect of temperature on the adiabatic laminar burning velocities of CH_4 + air and H_2 + air flames was analyzed. Available measurements were interpreted using correlation S_L = S_(LO) (T/T_O)~α. Particular attention was paid to the variation of the power exponent α with equivalence ratio at fixed (atmospheric) pressure. Experimental data and proposed empirical expressions for a as a function of equivalence ratio were summarized. They were compared with predictions of detailed kinetic models in methane + air and hydrogen + air flames. Unexpected non-monotonic behavior of α was found in rich methane + air flames. Modeling results are further examined using sensitivity analysis to elucidate the reason of particular dependences of the power exponent α on equivalence ratio.
