The Maximum Power Cycle: A Model for New Cycles and New Working Fluids
Abstract
The objective of this paper is to extend a previously presented finite-time thermodynamic framework that explains the conceptual differences between power and efficiency optimization and defines the Maximum Power cycle. The shape and the performance of the Maximum-Power cycle are used as criteria to study and evaluate alternative working fluids that can improve the performance of the power cycle for low temperature heat sources, such as solar energy and waste heat. In this study, pure fluids, non-azeotropic and azeotropic mixtures in a single or multi-stage Rankine cycle are considered. The results show that pressure-dependent azeotropic mixtures have the potential to improve the performance of the Rankine cycle. The results also show that the Maximum Power cycle provides a useful tool for studying power cycles and forms the basis for making design improvements.
