Abstract :
Experimental study by laser induced fluorescence (LIF) and numerical calculations of the influence of nanosecond barrier discharge on the preheated combustible mixture and flame have been performed. It was shown that in the channel of positive streamer propagating through combustible mixture of methane and air of atmospherical pressure hydroxyl radicals are produced. Absolute OH concentration values over the time after the discharge profiles have been obtained with resolution in time being up to 100 ns.
