Abstract

Reversible and irreversible (transport) phenomena in fluid-solid mixtures were analysed by the method of rational thermodynamics (nonlinear continuum mechanics). After formulating the balances and the second law of thermodynamics, constitutive equations for the binary mixture were proposed involving diffusion, heat conduction, and long-term memory characterized by an internal parameter. Viscosity and chemical reactions were disregarded. The final form of the constitutive equations is based on the constitutive principles of determinism, local action, memory, equipresence, objectivity, and on the entropic principle of Coleman and Noll. The cases of an isotropic solid and a mixture of fluids are also discussed.
