On thermodynamically consistent schemes for phase field equations

  title={On thermodynamically consistent schemes for phase field equations},
  author={Chaim Charach and Paul C. Fife},
This paper addresses the issue of thermodynamically consistent derivations of field equations governing nonisothermal processes with diffuse interfaces and their implications for interface conditions in the associated sharp interface theories. We operate within the framework of extended irreversible thermodynamics, allowing gradient terms to be present not only in the free energy and entropy densities but also in the internal energy, for both nonconserved and conserved order parameter theories… CONTINUE READING
