Contact Quantities and Non-Equilibrium Entropy of Discrete Systems
Muschik, Wolfgang
If a discrete non-equilibrium system is in contact with an equilibrium reservoir exchanging heat, power, and material with each other, a non-equilibrium non-additive entropy rate of the system can be defined by use of non-equilibrium contact quantities: contact temperature and dynamic chemical potentials. The integrability of the entropy rate and the corresponding Maxwell relations are investigated. The dissipation inequality is exploited for a simple material whose state space includes the time rate of the contact temperature. A non-equilibrium efficiency is introduced.
