The heated diverging channel technique for the measurement of laminar burning velocities was extended to incorporate measurements at elevated pressures. The evaluation of the combined influence of pressure and temperature on the fundamental combustion characteristics of CH4-air flames is realized through the new experimental facility. The laminar burning velocities of CH4-air mixtures at different equivalence ratios are reported for a pressure range (1–5 atm), and elevated temperatures of 350–650 K. The temperature exponent, α presents with the lowest value for marginally rich mixtures (ϕ = 1:1). The non-monotonic behavior of α is replicated at elevated pressures (2–5 atm). PREMIX calculations with commonly employed kinetic models (Aramco 2, GRI Mech 3.0) were compared with the present experiments. The predictions of Aramco 2 mechanism were in excellent agreement with the present measurements at high temperature and pressure conditions.
