Abstract


In this paper, by using a procedure of classical irreversible thermodynamics with internal variable (CIT-IT) some possible interactions among heat conduction, diffusion phenomena, viscous flows in fluid mixtures are studied. By introducing as internal variables n vectors which influence thermal and diffusion phenomena, phenomenological equations for these variables are derived. A general vector, J, consisting of heat and mass diffusion fluxes, is introduced and it is shown that, in isotropic media, J can be split in two parts: a first one which is governed by Fourier's law and the second one which satisfies to Maxwell-Cattaneo-Vernotte equation.
