Developed during recent two decades the new exposition of
thermodynamics developed by Gyfropoulos and Beretta [1] is aimed both to remove
logical circularities in teaching as well in removing obstacles for natural
generalization of this science. Keeping
the line of reasoning, following Gyftopoulos and Beretta, we will introduce the
basic concepts of thermodynamics without the notion of “heat” and “work”, and
will extend the Gyftopoulos and Beretta exposition into three-dimensional
continuum thermodynamics [2]. In proposed approach notion of “energy” and
“energy interactions” play a dominant role. The main problem connected with the
internal energy concept as a form of ,,energy storage’’ and the transformations
of different forms of energy are discussed. Balance of energy is finally
presented as a sum of internal, kinetic, potential and electromagnetic energies
in the system that are compensated by the total energy flux, which consists of
work, heat, chemical, electrical, magnetical and radiative energy fluxes at the
system boundaries [3]. The law of energy (and mass) conservation can be
considered as the most important one which is superior over any other laws of
nature. An example of “neo-classical”
Navier-Stokes equation, being a model thermodynamically consistent, is developed
and presented in details.
