Abstract
Application of hypersonic computational fluid dynamics models to low velocity vehicles is examined. Important modeling aspects such as chemical kinetics, electronic excitation/de-excitation mechanisms, and existence of equilibrium vs nonequilibrium conditions in the flow were examined. Flowfield properties and in-band radiances in the wavelength region of 0.25 µ in the vicinity of the stagnation streamline are given for a hemisphere with a radius of 0.0762 m. Comparison with recent shock tube data is also shown.
