Free-molecular gas flow through the high-frequency oscillating membrane

Abstract

The free-molecular gas flow through the membrane oscillating in its own plane was studied. Passing probability and velocity distribution function of gas molecules in the membrane were calculated depending on the dimensionless parameters characterizing the geometry of membrane channels, gas molecule mass, gas temperature, frequency and amplitude of the membrane oscillation. It has shown that the conductivity of the membrane for a given gas can be controlled by changing the parameters of forced oscillations.
