Chemical kinetics in combustion systems: The specific effect of energy, collisions, and transport processes

Abstract

Experimental result on the effect of selective translational and vibrational excitation of reactants in elementary combustion reactions using laser photolysis and time-resolved atomic line resonance absorption, laser-induced fluorescence and CARS spectroscopy are compared with the results of quasiclassical trajectory studies on ab initio potential surfaces and thermal rate parameters. Experimental data on collisional energy transfer from vibrationally highly excited polyatomic molecules and the pressure and temperature dependence of product formation in elementary combustion reactions with complex formation are discussed. Models for the prediction of transport coefficients in multicomponent mixtures, and recent model calculation and experiments on the coupling of chemical reactions and transport effects are presented.
