Theory of transport processes in a polyatomic gas
Abstract
A kinetic equation for a diatomic gas with ground-state electrons is solved by the Bogoliubov method using a relaxation gasdynamic approximation. The Wigner operator and sources in the equations of relaxation gas dynamics are determined in the local equilibrium and dissipative approximations, as are the kinetic coefficients and the relaxation pressure. A diatomic gas is considered in the case of the weak excitation of vibrational molecular states; the relaxation pressure and the relaxation times are determined using a two-moment approximation.
