Datailed investigations of nonequilibrium properties in nozzle-flows of an arc-heated wind tunnel and a hypersonic wind tunnel at NAL are performed. In particular, the production of NOx (NO, NO2, and N2O) is estimated in the nozzle-flows. It is shown that the main constituent of NOx at the exit of the nozzles is NO. However, in the exhaust gases of the arc-heated wind tunnel, the concentration of NOx is as much as 10,000ppm at usual conditions of operation ; the concentrations of NO and NO2 are shown to be in the same order. In order to explain the production of NO2 in the exhaust gases of the arc-heated wind tunnel, oxidation of NO is estimated by taking account of the pressure recovery in a chamber, and the isothermal compression in a rotary pump of the vacuum system. The latter model, termed “compression model”, is shown to be able to predict the production of a high concentration of NO2. In the hypersonic wind tunnel, it is shown that the concentration of NOx in the exhaust gas is of the order of 100 ppm under usual operating conditions, and the main constituent is infered to be NO. |
