Generalization of Onsager's principle and its application

  • 55 Accesses

  • 1 Citations


A principle is introduced to the thermodynamics of irreversible processes which generalizes the well-known Onsager principle. On the basis of this principle, an equation of heat conduction is derived with a finite velocity of heat propagation, and a system of equations of coupled thermoelasticity is set up.
