摘要：

State-to-state vibrational kinetics and transport models of a mixture containing triatomic CO2 molecules are developed. The models are implemented into a hypersonic boundary layer solver specially upgraded for this purpose. Although at the moment only vibrational-translational transitions in the bending mode (VT2), inter-mode exchanges within CO2 molecule (VV1-2-3), and inter-mode exchanges between molecules of different chemical species (VV1-2-CO) are taken into account, the approach can be generalized to include more complete kinetics. In order to overcome problems caused by the computational load of the state-to-state vibrational kinetics of a triatomic molecule, a Reduced Model is proposed and compared with the Full one.
