Non-Equilibrium Kinetics and Transport Properties in Reacting Flows in Nozzles

Abstract

Non-equilibrium vibration-dissociation kinetics, transport properties and dissociation rate coefficients in expanding flows are studied on the basis of different kinetic theory approaches: state-to-state, multi-temperature and one-temperature ones. The limits of validity of more simple models are discussed, the influence of non-equilibrium vibrational distributions, initial conditions, nozzle profile on the macroscopic parameters, heat transfer and reaction rates is investigated.
