title: Plasma-assisted combustion of methane using a femtosecond laser.
abstract: We first research the effects of femtosecond-laser-induced plasma (FLIP) on a laminar premixed methane/oxygen/nitrogen flame speed with a wide range of equivalence ratios (0.8-2.0) at atmospheric pressure. It is experimentally found that the flame speed increases by 30.8% at equivalence ratio 1.33, and the effects of the FLIP on the flame speed are more remarkable when the methane is rich. The self-emission spectra from the flame and the plasma are studied, and the presence of the oxygen atom is likely to be a key factor in enhancing flame speed.
