Global non-equilibrium thermodynamics of stationary states applied to the Rayleigh-Bénard convection
Robert HoÅyst, PaweÅ Jan Å»uk, Konrad GiżyÅski +3
Classical thermodynamics describes physical systems in thermodynamic equilibrium, characterized in particular by the absence of macroscopic motion. Global non-equilibrium thermodyn…

Continuous non-equilibrium transition driven by the heat flow
Yirui Zhang, Marek Litniewski, Karol Makuch +3
We discovered an out-of-equilibrium transition in the ideal gas between two walls, divided by an inner, adiabatic, movable wall. The system is driven out-of-equilibrium by supplyin…

Direction of spontaneous processes in non-equilibrium systems with movable/permeable internal walls
Robert HoÅyst, PaweÅ Jan Å»uk, Anna MacioÅek +2
The second law of equilibrium thermodynamics explains the direction of spontaneous processes in a system after removing internal constraints. When the system only exchanges energy…
