On Maximal Total Entropy Production Models for Steady Evaporation of a Calorically Perfect Polyatomic Gas
Niclas Bernhoff, Eddie Wadbro
This study investigates the boundary conditions for fluid-dynamic equations at the interface of a gas and its condensed phase during steady evaporation of a polyatomic gas. Evapora…

Two-temperature fluid models for a polyatomic gas based on kinetic theory for nearly resonant collisions
Kazuo Aoki, Niclas Bernhoff
A polyatomic ideal gas with weak interaction between the translational and internal modes is considered. For the purpose of describing the behavior of such a gas, a Boltzmann equat…

The half-space problem of evaporation and condensation for polyatomic gases and entropy inequalities
Niclas Bernhoff, Stephane Brull, Eddie Wadbro
This study investigates the steady Boltzmann equation in one spatial variable for a polyatomic single-component gas in a half-space. Inflow boundary conditions are assumed at the h…
