Research of burning of methane in a supersonic stream of the caused cross-section pulse-periodic laser radiation
The effect of a focused pulsed-periodic beam of a CO2 laser on initiation and evolution of combustion in subsonic and supersonic flows of homogeneous fuel–air mixtures (CH4 + air) is experimentally studied. The beam generated by the CO2 laser propagates across the flow and is focused by a lens at th...

| description | The effect of a focused pulsed-periodic beam of a CO2 laser on initiation and evolution of combustion in subsonic and supersonic flows of homogeneous fuel–air mixtures (CH4 + air) is experimentally studied. The beam generated by the CO2 laser propagates across the flow and is focused by a lens at the jet axis. The flow structure is determined by a schlieren system with a slot and a plane knife aligned in the streamwise direction. The image is recorded by a high speed camera with an exposure time of 1.5 μs and a frame frequency of 1000 s-1. The structure of the combustion region is studied by an example of inherent luminescence of the flame at the wavelengths of OH and CH radicals. The distribution of the emission intensity of the mixture components in the optical discharge region is investigated in the present experiments by methods of emission spectroscopy. |
