The problems of thermodynamic characterization of direct conversion process of thermal-to-electric energy in approximation of classic ideal gas

Well-known qualitative thermodynamic analogies between processes taking place in thermal electromotive force devices as well as in devices of direct conversion of thermal energy to electricity have not yet been confirmed by a really strict statement that could provide a way of quantitative characterization. The possibility of noncontradictory characterization of states of lots of free charges in substances and the processes of their diffusion and transport by means of such concepts as entropy and phase transitions is related with the choice of a suitable model meeting the requirements of completeness and non- contradiction. However, up to the present the problem of noncontradiction of the model of the classic ideal gas itself should be considered to be open, hence the well-known problem of mixture merging blending entropy hasn't been solved satisfactorily as far as classic solution within the frames of this model is concerned. This paper reports that it results in analyzing the main principal complications of the above-mentioned problem to advance from the traditional analogies to a more strict characterization
