NONEQUILIBRIUM THERMODYNAMICS OF BOUNDARY-CONDITIONS FOR RAREFIED-GASES AND RELATED PHENOMENA

The interrelation of the kinetic theory and non-equilibrium thermodyna mics is discussed. A procedure for deriving the boundary conditions fo r slightly rarefied gases is outlined. The entropy productions from th e processes associated with the non-uniform gas flow in channels with mobile walls and with the presence of an arbitrary geometric particle in non-uniform fluid are found. Using the entropy productions, the phe nomenological equations are obtained. New phenomena predicted on the b asis of these equations, and their experimental testing are discussed.
