Abstract
We previously derived the two-temperature Navier-Stokes system (a set of compressible Navier-Stokes equations with the translational and internal temperatures) for a polyatomic gas with slow relaxation of the internal modes from the ellipsoidal statistical model of the Boltzmann equation. In this paper, the appropriate boundary conditions for the two-temperature Navier-Stokes system are derived. The results are presented in a form that is applicable to practical applications immediately.
