On the definitions of entropy and temperature in the extended thermodynamics of irreversible processes

New definitions of entropy and temperature for uniform systems that fast exchange heat with the environment are considered. Instead of the known local equilibrium hypothesis, a local uniformity hypothesis is proposed. Within the proposed formalism of extended thermodynamics of irreversible processes, dual-phase-lag transfer equations are obtained. To cite this article: S.I. Serdyukov, C. R. Physique 8 (2007).
