Working fluid usage conditions
Thermoelectricity - Thermodynamics and applications

The conditions of use of the working fluid are crucial if we wish to obtain optimum system operation by placing the working fluid in the most appropriate thermodynamic conditions. In the case of a classic fluid such as water, it is clear that there are values of the pair of intensive variables (P, T) for which operation is optimal, or on the contrary mediocre, in terms of maximum work production and minimum entropy production. This is a very wide-ranging question, which cannot be exhausted in just a few lines. However, it is possible to define a few sensitive parameters that can be used to describe the impact of operating conditions on performance. In other words, it is important that control of the macroscopic intensive variables (μ,...
