  • Title: True nature of the Curzon-Ahlborn efficiency.
    Author: Apertet Y, Ouerdane H, Goupil C, Lecoeur P.
    Journal: Phys Rev E; 2017 Aug; 96(2-1):022119. PubMed ID: 28950453.
    Abstract:
    The Curzon-Ahlborn efficiency has long served as the definite upper bound for the thermal efficiency at maximum output power, and has thus shaped the development of finite-time thermodynamics. In this paper, we repeal the ruling consensus according to which it has a genuine universal character that can be derived from linear irreversible thermodynamics. We demonstrate that the Curzon-Ahlborn efficiency should instead properly be associated with a particular case of nonlinear heat engines, and we derive a generalized expression for the efficiency at maximum power beyond the restrictive case of linear models.
