The Quantum-Kinetic (Q-K) chemical reaction model is implemented in a Navier-Stokes solver, US3D, and tested on the Bow Shock Ultra Violet flight experiments. The chemical reaction rates predicted by the Q-K model are compared to a commonly used Park model for flows in thermal non-equilibrium. The results show that in thermal equilibrium the reaction rates between these two models are comparable. The Q-K model predicts greater rates for some chemical reactions and lesser rates for other reactions in an five species air chemistry model. In thermal non-equilibrium, the Q-K model maintains comparable rates near thermal equilibrium, while avoiding issues of strong thermal non-equilibrium seen in the Park model.The application of the Q-K model to the Bow Shock Ultra Violet flight experiments show that the model remains consistent with previous Navier-Stokes and DSMC computations over altitudes ranging from 53.5 km up to 87.5 km despite the enforcement of translational-rotational equilibrium. The commonly used Park model was unable to match this performance.
