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 ...

Finite Time Thermodynamic Analysis of Brayton Cycle

2017
The Brayton cycle was first proposed by George Brayton in 1870 for the reciprocating oil-burning engine and has been extensively used in power plants and aeroplanes since then. Today, it is used for gas turbines only where both the compression/expansion processes may operate on either in an open or a closed cycle.

Finite Time Thermodynamics of Brayton Refrigeration Cycle

2017
Most of the refrigeration cycles discussed so far involve change in phase of the working fluid (refrigerant) while undergoing through different stages. However, the gas refrigeration cycle is one in which the working fluid (refrigerant) remains as gas throughout the cycle, such as Brayton refrigeration cycle and Stirling/Ericsson refrigeration cycle ...

Minimizing Losses — Tools of Finite-Time Thermodynamics

1999
Finite-time thermodynamics was ‘invented’ in 1975 by R. S. Berry, P. Salamon, and myself as a consequence of the first world oil crisis. It simply dawned on us that all the existing criteria of merit were based on reversible processes and therefore were totally unrealistic for most real processes.
