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

open access: goldEntropy (Basel)
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 (Basel), 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

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

open access: yesEntropy (Basel)
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. As a consequence, excess entropy is generated, available work is reduced, and/or the maximally achievable efficiency is not ...

Association of Finite-Time Thermodynamics and a Bond-Graph Approach for Modeling an Endoreversible Heat Engine [PDF]

open access: goldEntropy, 2012
In recent decades, the approach known as Finite-Time Thermodynamics has provided a fruitful theoretical framework for the optimization of heat engines operating between a heat source (at temperature ) and a heat sink (at temperature ).

Temporal Asymmetry, Entropic Irreversibility, and Finite-Time Thermodynamics: From Parmenides–Einstein Time-Reversal Symmetry to the Heraclitan Entropic Arrow of Time [PDF]

open access: goldEntropy, 2012
In this paper, we combine the two universalisms of thermodynamics and dynamical systems theory to develop a dynamical system formalism for classical thermodynamics. Specifically, using a compartmental dynamical system energy flow model we develop a state-

Finite‐Time Thermodynamics and the Optimal Control of Chemical Syntheses   [PDF]

open access: greenZeitschrift Fur Anorganische Und Allgemeine Chemie, 2009
AbstractThe optimization of chemical processes that take place in a finite time constitutes an important application of finite‐time thermodynamics. In this study we investigate two generic optimal control problems for nucleation‐and‐growth based syntheses: the maximization of the amount of a crystalline solid phase generated via cooling from the melt ...

Reconstruction of $f(T)$ gravity: Rip cosmology, finite-time future singularities and thermodynamics [PDF]

open access: green, 2012
We demonstrate that there appear finite-time future singularities in $f(T)$ gravity with $T$ being the torsion scalar. We reconstruct a model of $f(T)$ gravity with realizing the finite-time future singularities.
