Paper Abstract

A novel approach to control the combustion processes by laser-induced excitation of vibrational or electronic states of target molecules is investigated. Target molecules are supposed to use to enhance the chain reactions in the gaseous combustible mixtures. The computations based on the extended physical-chemical model involving chemical processes with vibrationally and electronically excited molecules show that laser-induced excitation of O2 molecules to the a1Δg and b1Σg+ electronic states makes it possible to reduce considerably the ignition threshold in CH4(H2)/O2 (air) mixtures and to intensify the conversion of CH4 to H2 during oxidation of hel-rich CH4/air mixtures. A simultaneous excitation of O2 molecules to the electronic and vibration states enhances these processes additionally.
