This paper is devoted to the discussion of certain nonequilibrium states of gases and vapors in the free-molecular regime. In spite of the presence of temperature differences and, in some cases, of evaporation and condensation processes, the gas is shown to remain at rest. The case of a vapor in a tube of condensed phase, for which some numerical solutions are also given, is treated in some detail. (Authors)

Abstract

This paper is devoted to the discussion of certain nonequilibrium states of gases and vapors in the free-molecular regime. In spite of the presence of temperature differences and, in some cases, of evaporation and condensation processes, the gas is shown to remain at rest. The case of a vapor in a tube of condensed phase, for which some numerical solutions are also given, is treated in some detail. (Authors)
