1
Classical and nonlocal theories of nonequilibrium thermodynamics Peter Ván BUTE, Department of Chemical Physics Beyond local equilibrium Relocalizable theories Extended irreversible thermodynamics Non relocalizable theories Once again on the Ginzburg-Landau equation
2
Local equilibrium (= there is no microstructure)
Classical Irreversible Thermodynamics Local equilibrium (= there is no microstructure) Violations (nonlocality): in time (memory effects) in space (structure effects) dynamic variables current multipliers + ??
3
Nonlocalities:
4
? Weakly nonlocal extended thermodynamics
state space constitutive functions Liu procedure (Farkas’s lemma) ?
5
extended (Gyarmati) entropy
entropy current (Nyíri) (B – current multiplier)
6
Ginzburg-Landau (variational)
Second Law Variational (!)
7
? Ginzburg-Landau (thermodynamic, relocalized)
state space constitutive functions Liu procedure (Farkas’s lemma) ?
8
current multiplier isotropy
9
Ginzburg-Landau (thermodynamic, non relocalizable)
state space constitutive functions Liu procedure (Farkas’s lemma)
10
Conclusions Not everything is a balance
Internal variables are not omnipotent
