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 a¹Δ_g and b¹Σ_g⁺ 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.
