Abstract
The aerothermodynamics of thermo-chemical nonequilibrium carbon dioxide flows are studied. The chemical kinetics models of McKenzie and Park are implemented in separate three-dimensional computational fluid dynamics (CFD) codes. The codes incorporate a five-species gas model characterized by a translational-rotational and a vibrational temperature. Solutions are obtained for flow over finite length elliptical and circular cylinders for a free-stream condition of U∞ = 4.24km/s, T∞ = 1970K, and h∞ = 9.0MJ/kg. The computed flowfields are then employed to calculate Mach-Zehnder interferograms for comparison with experimental data. The accuracy of the chemicai kinetics models is determined through this comparison. Also, the methodology of the three dimensional thermo-chemieal nonequilibrium code is verified by the reproduction of the experiments.
