 Laminar burning velocity of oxy-methane flames in atmospheric conditionJeongseog Oh and Dongsoon Noh Energy, 2012, vol. 45, issue 1, 669-675 Abstract: The laminar burning velocity of oxy-CH4 flames in atmospheric conditions (300 K and 1 atm) was studied with a lab-scale Bunsen burner. CH chemiluminescence (CH*) was measured, and Schlieren photography was used to derive the laminar burning velocity. The experimental result was compared with the numerical calculation by using a GRI-Mech. ver. 3.0 in a CHEMKIN package. The global equivalence ratio (φG) of an oxy-CH4 mixture varied from φG = 0.5 to 2.0 in 0.1 steps in a laminar flow region. From the observation of the experimental measurements, the structure of laminar premixed flames was composed of a preheating zone, a reaction zone, and a burned gas region. The adiabatic flame temperature (TAd) was predicted to be 3056 K at φG = 1.1 from the numerical calculation. With the angle method, the laminar burning velocity (SL) of premixed oxy-CH4 flames at a normal temperature (300 K) and pressure (1 atm) was measured as SL = 2.95 m/s from Schlieren photographs and SL = 2.91 m/s from CH* images.
