title = "A two-level kinetic model for Rotational-Translational relaxations in a diatomic gas",
abstract = "This paper describes a simple two-level Rotational-Translational (RT) relaxation model with a single relaxation time for approximating the collision integral in the Generalized Boltzmann Equation (GBE). The model is validated by computing the shock structure at high Mach numbers by comparing the results with the solution of the complete GBE (same as Wang- Chang Uhlenbeck Equation except that it accounts for the degenerated energy states) for RT relaxations. Computations are then performed for the hypersonic flow of nitrogen past a 2-D blunt body in rotational nonequilibrium using both the two-level RT model and complete GBE; good agreement between the two solutions is obtained. However the computations with RT model are about twenty times faster than those with complete GBE.",
