This paper aims at opening a discussion about the procedure for negentropy application in thermoeconomics, by showing that: (i) the original procedure leads to some inconsistencies; and (ii), a more recent approach takes all the negentropy advantages, without leading to inconsistencies, by applying the negentropy as a physical exergy component flow.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:The introduction of the negentropy in thermoeconomics represented a great advance in the discipline, since this magnitude allows quantifying the condenser product in a steam cycle plant, which was not possible before because the condenser is a dissipative component, whose product cannot be expressed in terms of exergy.
📊
Key Findings & Data:However, most authors have been applying the negentropy as a fictitious flow, joined up with the exergy flow.
💡
Conclusion & Impact:This paper aims at opening a discussion about the procedure for negentropy application in thermoeconomics, by showing that: (i) the original procedure leads to some inconsistencies; and (ii), a more recent approach takes all the negentropy advantages, without leading to inconsistencies, by applying the negentropy as a physical exergy component flow.

Abstract

The introduction of the negentropy in thermoeconomics represented a great advance in the discipline, since this magnitude allows quantifying the condenser product in a steam cycle plant, which was not possible before because the condenser is a dissipative component, whose product cannot be expressed in terms of exergy. However, most authors have been applying the negentropy as a fictitious flow, joined up with the exergy flow. This paper aims at opening a discussion about the procedure for negentropy application in thermoeconomics, by showing that: (i) the original procedure leads to some inconsistencies; and (ii), a more recent approach takes all the negentropy advantages, without leading to inconsistencies, by applying the negentropy as a physical exergy component flow.

Özet

Negentropinin termoekonomiye girişi bu disiplinde büyük bir ilerlemeyi temsil etmiştir çünkü bu büyüklük bir buhar çevrim santralindeki kondenser ürününün nicelendirilmesini sağlamıştır. Kondenser, ürünü ekserji açısından ifade edilemeyecek harcayıcı bir parça olduğundan bu daha önce olası değildi. Bununla birlikte çoğu yazar negentropiyi ekserji akışı ile birleşmiş hayali bir akış olarak uygulamaktadırlar. Bu makale termoekonomideki negentropi uygulaması prosedürü için (i) orijinal prosedürün bazı tutarsızlıklara yol açtığını ve (ii) yeni yaklaşımın tutarsızlıklara yol açmadan negentropiyi fiziksel ekserji bileşenli akış olarak uygulayarak tüm negentropi avantajlarını barındırdığını göstererek bir tartışma başlatmayı hedeflemektedir.
