Research Abstract

A time-dependent collisional-radiative model for air plasma has been developed to study the effects of nonequilibrium atomic and molecular processes on the population density in high enthalpy flow. The unsteady nature of pulsively heated air plasma was investigated. When the ionization relaxation time is of the same order as the time scale of a heating pulse, the effects of unsteady ionization are important for estimating air plasma states. From parametric computations in wide temperature and density range, we suggested the appropriate conditions for physical models of plasma internal states.
