TY - Type of reference TI - Augmented Curzon-Ahlborn modelling of Carnot engine AU - Michel Feidt AU - Gwilherm Siochan AB - This paper reconsiders the modelling of Curzon-Ahlborn dedicated to Carnot engine. A modified model is proposed, taking account of the period (duration) of the cycle. It allows a two steps optimization, by following a model incorporating internal irreversibility of the cycle. New results are obtained. We note particularly comparison of various approaches: with thermodynamics transformations according to Curzon and Ahlborn proposal versus mean values over the cycle according to Chambadal proposal. It confirms the interest of the description of irreversibilities with entropy production method preferably to the ratio method. This new approach may give rise to an extension currently under development to our initiative.
