EXPERIMENTAL DETERMINATION OF GAS PROPERTIES AT HIGH TEMPERATURES AND/OR PRESSURES

Abstract

The available viscosity and thermal conductivity data in helium, argon, hydrogen, and nitrogen are reviewed. Deviation charts vs temperature are drawn up for each of the gases of interest in the temperature range 200-2500K. High temperature thermal conductivity measurements in air, argon and nitrogen are also reviewed at temperatures between 2000 and 12,000K. The methods of measuring thermal conductivity and viscosity are discussed with emphasis on the extension of available techniques to higher temperatures and/or pressures. Major emphasis is placeed on constricted arc, heat transfer, schlieren, and ultrasonic techniques. Finally, measurements of helium thermal conductivity in the temperature range approx. 400-3000K by the ultrasonic technique in the shock tube are presented.
