Abstract
Using an ultrasonic interferometer in the temperature range from 293 to 393 K at pressures from 0.13 to 1.5–2.8 MPa, the speed of sound (U) was measured in helium-xenon gas mixtures with a helium content of 60.34; 71.72 and 85.32 at. %. The measurement errors of temperature, pressure, and speed of sound were ±20 mK, ±4 kPa, and ± (0.15–0.30) %, respectively. By approximating the experimental data for each composition, equations were obtained to describe changes of the speed of sound as a function of pressure and temperature over the entire measurement range. The existing reference and experimental data on the speed of sound in inert gases and He-Xe mixtures were analyzed. A method for calculating U of mixtures with a helium content above 71.7 at. % He to a temperature of 1500 K and a pressure of up to 7 MPa was developed.
期刊介绍:
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
