Escoamento Rotativo de Gas Rarefeito Entre Dois Cilindros Coaxiais COM Condicoes de Escorregamento (Slip Condition) (Rotational Flow of Rarefied Gas between Two Coaxial Cylinders with Slip Conditions)

摘要

A rotational flow of rarefied gas between two coaxial cylinders was considered. The external one was rotating, the internal one stationary. Knudsen number was assumed to be of the order of unity. Due to the formation of rarefied nucleus at the internal cylinder, boundary conditions at this point was considered to be the slip condition. The problem was solved for variable transport coefficients (i.e., variable viscosity and thermal conductivity). The distribution of velocity, temperature and some other parameters was obtained.
