Abstract
- This note is our comments to the paper entitled, “Equivalence between the application of entransy and entropy generation” (Oliveira and Milanez, 2015). In this paper, the authors showed the equivalence between the application of the concepts of entransy and entropy by using several application examples including three physical models of solar energy collectors and a physical model of a sensible heat storage system. The main expressions regarding entransy in this paper come from our conference paper entitled, “Entransy transfer analysis and its application to optimizing irreversible thermodynamic cycles” (Wu and Guo, 2007). However, the authors did not distinguish between the entransy, the entransy transfer, and the thermodynamic entransy transfer. The application of which was shown to be equivalent to that of entropy generation by the authors using four examples, is the thermodynamic entransy transfer rather than the entransy transfer. Hence, the conclusion that the applications of entransy and entropy are equivalent is not appropriate. [ABSTRACT FROM AUTHOR]
