Experimental Study of the Real Gas Effects of Nitrogen and Air to 3000 Atmospheres and 3500 K

Abstract

A free piston compression tube has been used to generate samples of nitrogen and air test gases at pressures up to 3000 kg/sq cm and 3500 K. Measurement of pressure, temperature and volume during part of the cycle has been made. The experiments use piezoelectric transducers, a sodium line reversal technique and an eddy-current transducer. The main emphasis in this phase of a continuing research program is on the generation of data in nitrogen and air over the widest range possible in the facility. Regions in the Mollier chart in which measurements become more uncertain are specified. Extensive analysis of the data has illustrated that larger differences between experiment and equation of state models have been found than earlier results indicated. Other interpretations of the differences seen are also discussed.
