Compressor Power and Efficiency Optimization: A Finite-Time Thermodynamics Approach [PDF]

open access: goldEntropy
This paper presents a theoretical optimization of an endoreversible compressor under steady-state conditions. A parametric study using finite-time thermodynamic principles highlights the effect of external irreversibilities on compressor performance.

Thermoelectric Efficiency of Silicon–Germanium Alloys in Finite-Time Thermodynamics [PDF]

open access: goldEntropy, 2020
We analyze the efficiency in terms of a thermoelectric system of a one-dimensional Silicon–Germanium alloy. The dependency of thermal conductivity on the stoichiometry is pointed out, and the best fit of the experimental data is determined by a nonlinear

The First Fifty Years of Finite-Time Thermodynamics [PDF]

open access: goldEntropy
The year 1975 marked the beginning of an entirely new direction for thermodynamics with the publication of Curzon and Ahlborn’s innocent-looking short paper “Efficiency of a Carnot engine at maximum power output” [...]

Finite-Time Thermodynamics and Complex Energy Landscapes: A Perspective [PDF]

open access: yesEntropy
Finite-time thermodynamics (FTT) describes the study of thermodynamic processes that take place in finite time. Due to the finite-time requirement, in general the system cannot move from equilibrium state to equilibrium state.

Heat leak term: A signature of irreversibility in analysing the actual SI engine cycle using finite-time thermodynamics [PDF]

open access: diamondFME Transactions, 2022
Due to the headway in innovations, it ends up noticeably unavoidable to do a complex thermodynamic analysis of thermal systems. The major problem faced during the development of a thermodynamic model for the analysis is to check the feasibility of the ...

Quantum Thermodynamics: A Dynamical Viewpoint

open access: yesEntropy, 2013
Quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. The viewpoint advocated is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics

Global linear-irreversible principle for optimization in finite-time thermodynamics [PDF]

open access: green, 2018
There is intense effort into understanding the universal properties of finite-time models of thermal machines---at optimal performance---such as efficiency at maximum power, coefficient of performance at maximum cooling power, and other such criteria. In
