Abstract
In a previous paper by the present authors and H.-W. Kuo [S. Kosuge et al, J. Stat. Phys. 177, 209 (2019)], the ellipsoidal-statistical (ES) model of the Boltzmann equation for a polyatomic gas with constant specific heats (calorically perfect gas), proposed by P. Andries et al. [P. Andries et al., Eur. J. Mech. B/Fluids 19, 813 (2000)], was extended to a polyatomic gas with temperature-dependent specific heats (thermally perfect gas), and the associated Navier–Stokes equations were derived by the Chapman–Enskog procedure. In this paper, the new model, together with the Navier–Stokes equations, is summarized. Then, the form of the appropriate boundary conditions for the latter equations is derived by the analysis of the Knudsen layer.
