INVISCID NON-EQUILIBRIUM FLOW OF AN EXPANDED AIR PLASMA. ABSTRACT OF DISSERTATION.
Abstract
It was shown that a high degree of chemical and vibrational non-equilibrium can exist in the expanded flow from an arc-heated wind tunnel. The experimental studies substantiate the existence of an effective flow freezing point for the chemical reactions. The measured nitrogen vibrational temperatures were found to be significantly lower than predicted by the application of shock tube excitation times in a Landau-Teller relaxation calculation. The low vibrational temperatures measured in the experimental studies suggest that the effects of vibrational freezing on the properties of the wind tunnel test gas may not be as severe as anticipated. The experimental studies demonstrate that the thermochemical state of the effluent generated by the arc-heated wind tunnel can be defined reasonably well. (Author)
