Non-equilibrium theories of rarefied gases: internal variables and extended thermodynamics
Non-equilibrium theories of rarefied gases: internal variables and extended thermodynamics
Limits of classical constitutive laws such as Fourier and Navier-Stokes equations are discovered since decades. However, the proper extensions -- generalizations of these are not unique. They differ in the underlying physical principles and in modeling capabilities. In this paper, two different theories are discussed and compared to each other, …
