Study of helium permeability for silica microspheres
This paper presents the study of permeability of helium through walls of hollow glass silica microspheres, which can be used as membranes for gas flow. The study was performed in a special setup for measuring the kinetic sorption curves for helium at given pressure and temperature. A mathematical model based on a mono-dispersion distribution was used for approximating the experimental data. The data was obtained for the temperature range 21.5–110.0 °C. The helium permeability of microsphere walls and the activation energy for helium sorption by microspheres were defined for this temperature range.
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.
