Non-linear dynamics of the generalized Carnot problem: maximum work received in a finite time from a system of two continua with different temperatures.

Type of article: Article

Summary

The author considers applications of the optimization theory based on a classical (energy-like) Hamiltonian for various active continuous and cascade processes associated with the theory of a body in a bath, when the indirect exchange of the energy occurs through the working fluid of the participating engine, refrigerator or heat pump. The results show that the criteria known from the classical availability theory should be replaced by limits obtained for finite time processes which are closer to reality. Hysteretic properties which arise as the difference between the work supplied and the work delivered are effective.
