Determination of laminar flame speed of methaneair flames at subatmospheric conditions using the cone method and ch* emission
Experimental measurements of laminar fl ame speed for premixed methane-air fl ames were carried out for different equivalence ratios at subatmospheric conditions, 852 mbar and 298 K. The fl ames were obtained using a rectangular port burner with a water cooler system necessary to maintain the temper...
