Endo-irreversible thermo-mechanical engine with new concept of entropy production action coefficient
Thermostatics of CARNOT engines has been extended by more recent research based on endo-reversible model. Our model assumes exo-reversibility but endo-irreversibility to determine new upper-bound to thermomechanical conversion. We propose a functional expression of entropy production related to transformation cycle durations. This approach analyses the energy, entropy and power consequences. We introduce a new concept of entropy production actions that results in three optimums : maximum energy related to transformation durations, maximum energy associated with equipartition of entropy actions, optimal power for given period cycle.
