Název v původním jazyce

On possible formulation of the extended irreversible thermodynamics and the thermodynamics with internal variables

Popis výsledku v původním jazyce

Different formulations of the irreversible thermodynamics exist. Depending on the distance from the equilibrium state and the characteristic time the main theories are the classical theory (CIT), the thermodynamics with inter-nal variables (IVT) and theextended theory (EIT). Sometimes it is not easy to choose the proper theory and to use it efficiently with respect to applied problems considering different fields of interest. Especially EIT is ex-plained mainly for very special choice of the dissipative fluxes under specific presumptions. The paper tries to formulate EIT and IVT in a simple, unified but enough general form. The basic presumptions for EIT are shown and discussed, further a possible generalization is proposed. The formulation allows theintegration of IVT and EIT even for the mixture of chemically interacting components and diffusion. The application of the formulation is demonstrated on an example.
