Abstract

The paper presents three collisional-radiative models developed to investigate non-equilibrium chemistry andradiation in hypersonic shock tubes operating with different planetary atmospheres. An hybrid collisional-radiative model,employing the state-to-state kinetics of electronically excited states of molecules and the multi-temperature approximationfor the vibrational degree of freedom is presented first, and applied to the numerical rebuilding of experimental shock tubeemission spectra. Next, an hybrid collisional-radiative model for ionized air is presented. This model consider the state-tostateapproach for electronic states of atoms and the multi-temperature model for the vibrational populations of diatomicmolecules in their ground electronic state. A radiative transport equation is also solved to determine radiative source termsin the kinetic scheme and the enthalpy production due to radiation. The third model considers the state-to-state collisionalradiativemodel of Jupiter's atmosphere, self-consistently coupled with the Boltzmann equation for free electrons and theradiative transfer equation for the radiation transport in one-dimensional slab geometry.
