Study of the Real Gas Effects of Nitrogen and Air at High Densities and Temperatures
Abstract
A free piston compression tube has been used to generate samples of nitrogen and air test gases pressures up to 3000 kg/sq cm and 2300K. A description of the measurement of pressure, temperature and volume (driving part of the cycle) has been made. Calculations and experiments have been carried out which have indicated the level of uncertainty of measurement of these parameters. The results of the experiments in nitrogen have shown that agreement with the equation of state at low conditions is i.e. 1700K and 1400 kg/sq cm good, but a systematic deviation from that expected is obtained at higher conditions. The deviations from that expected from published tables describing the thermodynamic state of air are found to be large, but these may be due to a problem of contamination caused by the reactive nature of hot, high pressure oxygen.
