PHOTOCHEMICAL IGNITION OF GASEOUS FUEL-OXIDIZER MIXTURES AT SUBATMOSPHERIC PRESSURES.

Abstract

Experimental and analytical results are presented on the radiative initiation of sustained combustion in unsensitized, methane-oxygen-nitrogen and hydrogen-oxygen-nitrogen mixtures at room and slightly elevated temperatures and at fuel-oxygen partial pressures from 25 to 600 torr. Minimum irradiance required to photochemically initiate combustion, photochemical ignition delay time and reaction front propagation velocity were measured for the range of conditions stated above and for various wavelength ranges in the 1000-2000 A region.
