CO2 State-to-State Kinetics and Transport in a Hypersonic Boundary Layer: Preliminary Results

State-to-state vibrational kinetics and transport properties of a mixture containing carbon dioxide molecules are studied. Theoretical models are developed and implemented in a hypersonic boundary layer solver. Various vibrational relaxation channels are considered, and the influence of complex kinetic processes on the flow parameters and heat flux is evaluated. A simpler reduced model is developed to keep the computational cost reasonable.
