Effect of inelastic collisions of polyatomic
gas molecules on the Burnett slip coefficient

The problem of gas Burnett sliding along a flat surface is solved under the proposed ki-
netic model for the polyatomic gas with molecule rotational degrees of freedom, with due
regard for the rotational-translational transitions of the gas molecules. The Burnett slip
coefficient is obtained as a function depending on the frequency of inelastic collisions of
the gas molecules and the accommodation coefficient of tangential momentum.
Keywords
: Burnett slip, polyatomic gas, molecule rotational degrees of freedom.
