When gas supports with respect to vibro-stability are calculated it is necessary to consider the heat process of the work of the supports because, in general, compression and expansion of the gas are followed by changes in its temperature. A complete study of the non-stationary flow of a viscous heat-conducting gas within slip gas supports presents considerable difficulties due to the non-linearity of the differential equations that describe the gas motion. The study looks at the case of the non-stationary gas flow between parallel vibrating plates on the basis of the exact equations of hydrodynamics with the ph-method, and the effect of heat transfer and inertial forces on the compression effect is brought out. Calculations show that when the temperature of at least one plate is maintained constant, the state of the gas is close to isothermal. Inertial effects in the laminar layer are negligibly small during moderate amplitudes of oscillation.
