The authors base the description of heat and mass transfer processes in a polyatomic gas in a flat channel on a model equation, which takes into account the possibility of the excitation of two types of internal energy of the molecules: rotational and vibrational. Numerical estimations are made of the contribution of the internal degrees of freedom of the molecules to the fluxes. The results of these studies can be used to justify and design experimental methods for determining the characteristic relaxation times in polyatomic gases.
