Current Trends in Finite-Time Thermodynamics

Angewandte Chemie - International Edition, 2011
AbstractThe cornerstone of finite‐time thermodynamics is all about the price of haste and how to minimize it. Reversible processes may be ultimately efficient, but they are unrealistically slow. In all situations—chemical, mechanical, economical—we pay extra to get the job done quickly. Finite‐time thermodynamics can be used to develop methods to limit

Thermal cycles in classical thermodynamics and nonequilibrium thermodynamics in contrast with finite time thermodynamics

Energy Conversion and Management, 2002
There appear to be some fundamental disagreements between those scientists and engineers who adhere to the principles of macroscopic classical thermodynamics and those who adhere to the principles of finite time thermodynamics. In many instances, the disagreements can be traced to differing assumptions concerning fundamental principles, definitions ...

Finite-Time Thermodynamics [PDF]

open access: yes, 2022
The theory around the concept of finite time describes how processes of any nature can be optimized in situations when their rate is required to be non-negligible, i.e., they must come to completion in a finite time.

Optimization of thermal systems based on finite-time thermodynamics and thermoeconomics

open access: yesProgress in Energy and Combustion Science, 2004
The irreversibilities originating from finite-time and finite-size constraints are important in the real thermal system optimization. Since classical thermodynamic analysis based on thermodynamic equilibrium do not consider these constraints directly, it

From Finite Time to Finite Physical Dimensions Thermodynamics: The Carnot Engine and Onsager’s Relations Revisited

open access: yesJournal of Non-Equilibrium Thermodynamics, 2018
Many works have been devoted to finite time thermodynamics since the Curzon and Ahlborn [1] contribution, which is generally considered as its origin. Nevertheless, previous works in this domain have been revealed [2], [3], and recently, results of the ...

Thermodynamics in finite time

Physics Today, 1984
Until the 19th century, technology was essentially the domain of skilled artisans and constructors who relied on practical experience to design and build their machines. One of the first efforts to use physical theory to study the functioning of machines was undertaken by the French engineer Sadi Carnot. Motivated by the concern of the French about the
