State-to-state reaction rates in gases with vibration-electronic-dissociation coupling: the influence on a radiative shock heated CO flow

In the present paper, a theoretical model for the state specific dissociation-recombination rate coefficients taking into account electronically excited molecular states is proposed. The dissociation model generalizes the well known Treanor-Marrone model whereas the recombination model is derived using the microscopic detailed balance principle. The developed models are then applied for the investigation of a non-equilibrium high temperature CO flow with strongly coupled vibrational and electronic energy transitions, dissociation, recombination, and radiative transitions. The influence of dissociation from electronically excited states on the flow parameters is found to be important.
