A parallel finite element solver is developed for hypersonic flows with frozen chemistry. The finite element formulation is edge-based with flow stabilization via a Roe scheme. The flow solver is loosely-coupled with a two-temperature thermal non-equilibrium solver. Numerical experiments are performed to assess the accuracy and efficiency of the proposed approach.
