Three-Temperature Model Applied to Thermochemical Non-Equilibrium Reentry Flows in 2D—Seven Species

In this work, a study involving the fully coupled Euler and Navier-Stokes reactive equations is performed. These equations, in conservative finite volume contexts, employing structured spatial discretization, on condition of thermochemical non-equilibrium, are analyzed. High-order studies accomplished using Spectral method Streett, Zang, Hussaini. The high enthalpy hypersonic flows around circumference, reentry capsule, along blunt body, double ellipse two-dimensions simulated. Van Leer, Liou Steffen Jr., Steger Warming flux vector splitting algorithms applied to execute numerical experiments. Three temperatures, which translational-rotational temperature, vibrational electron used accomplish comparisons. Excellent results were obtained with minimum errors inferior 6.0%. key contribution work correct implementation three temperature model perform simulations, as well description energy exchange mechanisms more realistic simulations.
