When theories and experiments meet: rarefied gases as a benchmark of non-equilibrium thermodynamic models
Róbert Kovács, Patrizia Rogolino, David Jou
The role of thermodynamics in deriving constitutive equations is unique, and various approaches have been developed in the last decades. In the present paper, the frameworks of Ext…
Ballistic-diffusive model for heat transport in superlattices and the minimum effective heat conductivity
Federico Vázquez, Péter Ván, Róbert Kovács
There has been much interest in semiconductor superlattices because of showing very low thermal conductivities. This makes them especially suitable for applications in a variety of…
Numerical treatment of nonlinear Fourier and Maxwell-Cattaneo-Vernotte heat transport equations
Róbert Kovács, Patrizia Rogolino
The second law of thermodynamics is a useful and universal tool to derive the generalizations of the Fourier's law. In many cases, only linear relations are considered between the…
Variational principles and thermodynamics
Péter Ván, Róbert Kovács
Variational principles play a fundamental role in deriving evolution equations of physics. They are working well in case of nondissipative evolution but for dissipative systems the…
Thermodynamical extension of a symplectic numerical scheme with half space and time shift demonstrated on rheological waves in solids
Tamás Fülöp, Róbert Kovács, Mátyás Szücs +1
On the example of the Poynting-Thomson-Zener rheological model for solids, which exhibits both dissipation and wave propagation - with nonlinear dispersion relation -, we introduce…
