Rheological modeling with GENERIC and with the Onsager principle
Miroslav Grmela
In this paper we compare three frameworks for modeling flows of complex fluids: (i) local conservations of mass, momentum and energy, (ii) GENERIC, and (iii) Onsager principle. The…
Landau Theory of Dynamic Critical Phenomena in the Rayleigh-Benard System
Miroslav Grmela
Physics involving more details than hydrodynamics is needed to formulate rate thermodynamics of the Rayleigh-Bénard system. The Boussinesq vector field is approached in the space o…
Roles of Energy and Entropy in Multiscale Dynamics and Thermodynamics
Miroslav Grmela
Multiscale thermodynamics is a theory of relations among levels of description. Energy and entropy are its two main ingredients. Their roles in the time evolution describing approa…
Thermodynamics and Rate Thermodynamics
Miroslav Grmela
Approach of mesoscopic state variables to time independent equilibrium sates (zero law of thermodynamics) gives birth to the classical equilibrium thermodynamics. Approach of fluxe…
