A Geometrie Perspective on Irreversible Thermodynamics with Internal Variables
The thermodynamics of simple materials is analysed from a geometrical point of view. The model provides a suitable framework for dissipative structures arising during the evolution of the system.
A geometric model for the thermodynamics of continuous media is constructed, providing a clearer meaning to the commonly used concept of `processes` and `transformations`. The aim is to elucidate a
Thermodynamic Transformations in Magnetically Polarizable Undeformable Media
Abstract In this paper the problem of magnetically undeformable polarizable media in the presence of an electromagnetic field is analyzed from a thermodynamic viewpoint. The thermodynamic
Generalized heat-transport equations: parabolic and hyperbolic models
We derive two different generalized heat-transport equations: the most general one, of the first order in time and second order in space, encompasses some well-known heat equations and describes the
On a thermodynamical model for dielectric relaxation phenomena
In this paper an extension of Debye's model by considering Kluitenberg's theory on dielectric relaxation phenomena is proposed. Following Kluitenberg's dielectric theory, it is supposed that the
Influence of nonlinear effects on the efficiency of a thermoelectric generator
We propose a nonlinear model for thermoelectric coupling which is based on the thermomass theory for heat conduction. We show that in this model, the second Kelvin relation and the classical Onsager
Mechanical model for relaxation phenomena in viscoanelastic media of order one
Abstract In this paper a model for viscoanelastic isotropic material in the formalism of Kluitenberg's theory on mechanical relaxation phenomena is considered. Moreover an expression of the complex
Thermoelectric efficiency of graded SicGe1–c alloys
We consider SicGe1–c graded systems of length L = 3 mm and L = 100 nm, under the action of an electric field E, and crossed by an electrical current i, the two sides of which are kept at two
Minimal Entropy Production and Efficiency of Energy Conversion in Nonlinear Thermoelectric Systems with Two Temperatures
Abstract In this paper we determine the physical conditions ensuring that the efficiency of a thermoelectric nanowire with two temperatures is optimal. We consider the case in which the entropy for
Numerical treatment of nonlinear Fourier and Maxwell-Cattaneo-Vernotte heat transport equations
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 thermodynamic
