State-to-state models for CO2 molecules: From the theory to an application to hypersonic boundary layers

► We develop a state-to-state vibrational kinetics model of a mixture containing CO2. ► We develop a state-to-state transport model of a mixture containing CO2. ► We develop a code coupling hypersonic boundary layer equations to the previous models. ► We propose a Reduced Model to overcome the computational load of a triatomic molecule. ► We calculate vibrational distributions and transport properties in the boundary layer.
