Abstract

Fluid-dynamic-type equation for the Knudsen compressor to the case of polyatomic gases is derived on the basis of the ellipsoidal statistical (ES) model of the Boltzmann equation. It is shown that the resulting equation is the same as that for monatomic gases, except for a minor modification to the transport coefficients in that equation by the Prandtl number adjustment.
