Finite-time thermodynamics and thermodynamic length

Revue Générale de Thermique, 1996
Abstract Finite-time thermodynamics is the extension of traditional thermodyamics to deal with processes which have explicit time or rate dependencies. In doing so the macroscopic measurable description of thermodynamic systems is preserved while irreversibilities, and the hence entropy production, are introduced via empirical rate equations or ...

Thermodynamics for processes in finite time

Accounts of Chemical Research, 1984
Thermodynamics serves several functions for chemistry and ita sister sciences and technologies. The first of these historically, and still one of the most important, is the provision of limits on the performance of proceases and devices. The very origins of thermodynamics developed from the creative ways people addressed the problem of how beat to pump

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

Optimization in finite-reservoir finite-time thermodynamics

Physical Review E, 2014
A necessary condition to optimize work output is obtained for general heat engines working between two finite-sized heat reservoirs in a given period of time τ, with the amount of heat received from the hot reservoir being fixed for all possible realizations of the process.

Maximal work problem in finite-time thermodynamics

Physical Review E, 2000
In this paper three problems are considered: (a) the maximal work that can be produced in a finite time in a thermodynamic system; (b) the minimal work which must be done in order to transform an equilibrium thermodynamic system into a number of subsystems that are out of equilibrium with each other in finite time; and (c) the maximal power that can be

Finite-Time Thermodynamics and Endoreversible Heat Engines

International Journal of Mechanical Engineering Education, 1993
An endoreversible heat engine is an internally reversible and externally irreversible cyclic device which exchanges heat and power with its surroundings. Classical engineering thermodynamics is based on the concept of equilibrium. Time is not considered in the energy interactions between the heat engine and its environment. On the other hand, although

Finite-time thermodynamics and the gas-liquid phase transition

Physical Review E, 2007
In this paper, we study the application of the concept of finite-time thermodynamics to first-order phase transitions. As an example, we investigate the transition from the gaseous to the liquid state by modeling the liquification of the gas in a finite time.

Finite-Time Thermodynamics and Simulated Annealing

1996
Finite-time thermodynamics is the extension of traditional reversible thermodynamics to include the extra requirement that the process in question goes to completion in a specified finite length of time. As such it is by definition a branch of irreversible thermodynamics, but unlike most other versions of irreversible thermodynamics, finite-time ...
