Abstract
A model kinetic equation for accurate description of rarefied polyatomic gases is introduced. The collisions of polyatomic gas particles are modeled by a two term collision operator, one modeling only exchange of translational energy and the other modeling exchange of both translational and internal energies. The proposed kinetic model, which is an extension of the Rykov and Shakov models, predicts correct relaxation of higher moments and delivers the accurate Prandtl (Pr) number. Also, the model has a non-linear H-theorem. The model is used to construct a system of 36 moment equations, which is closed by the generalized Grad method for polyatomic gases.
