In this paper, non-equilibrium kinetics and transport processes in a viscous hypersonic flow of reacting CO 2 /CO/O 2 /C/O mixture are studied on the basis of the kinetic theory methods. Vibrational excitation of CO 2 , CO and O 2 molecules as well as non-equilibrium dissociation, recombination and exchange reactions are taken into account and the influence of non-equilibrium kinetics on transport properties is studied. A five-temperature model for a non-equilibrium flow suitable for applications is derived from the kinetic theory and used for the evaluation of transport properties of considered mixture under re-entry conditions. The paper presents the closed set of non-equilibrium flow equations, expressions for transport properties and results of calculations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
