Onsager coefficients of a Brownian Carnot cycle [PDF]

open access: yesThe European Physical Journal B, 2010
We study a Brownian Carnot cycle introduced by T. Schmiedl and U. Seifert [Europhys. Lett. \textbf{81}, 20003 (2008)] from a viewpoint of the linear irreversible thermodynamics.

Carnot Theorem Revisited: A Critical Perspective [PDF]

open access: yesEntropy
After a brief review of Carnot’s everlasting contributions to the foundations of thermodynamics, we critically examine the consequences of the Carnot theorem, which leaves behind some lingering questions and confusion that persist even today. What is the

Onsager coefficients of a finite-time Carnot cycle [PDF]

open access: yesPhysical Review E, 2009
We study a finite-time Carnot cycle of a weakly interacting gas which we can regard as a nearly ideal gas in the limit of $T_\mathrm{h}-T_\mathrm{c}\to 0$ where $T_\mathrm{h}$ and $T_\mathrm{c}$ are the temperatures of the hot and cold heat reservoirs ...

On reversible, endoreversible, and irreversible heat device cycles versus the Carnot cycle: a pedagogical approach to account for losses [PDF]

open access: green, 2016
In this work we analyze the deviations of reversible cycles (for both heat engines and refrigerators) from the corresponding Carnot cycle operating between the same extreme temperatures, and deviations of irreversible cycles from their corresponding ...

OTEC Maximum Net Power Output Using Carnot Cycle and Application to Simplify Heat Exchanger Selection [PDF]

open access: yesEntropy (Basel), 2019
Ocean thermal energy conversion (OTEC) uses the natural thermal gradient in the sea. It has been investigated to make it competitive with conventional power plants, as it has huge potential and can produce energy steadily throughout the year.

Improved Chambadal Model with New Optimization Results [PDF]

open access: yesEntropy
This paper presents a continuation of the Chambadal model optimization of the irreversible Carnot engine. We retrieved the results presented in the Special Issue “Carnot Cycle and Heat Engine Fundamentals and Applications II” and enriched them with new ...

Efficiency at maximum power output of an irreversible Carnot-like cycle with internally dissipative friction [PDF]

open access: green, 2012
We investigate the efficiency at maximum power of an irreversible Carnot engine performing finite-time cycles between two reservoirs at temperatures $T_h$ and $T_c ...

Carnot Cycles in a Harmonically Confined Ultracold Gas across Bose–Einstein Condensation [PDF]

open access: yesEntropy, 2023
Carnot cycles of samples of harmonically confined ultracold 87Rb fluids, near and across Bose–Einstein condensation (BEC), are analyzed. This is achieved through the experimental determination of the corresponding equation of state in terms of the ...
