Thermodynamics for processes in finite time
Accounts of Chemical Research, 1984Thermodynamics 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

Thermodynamics in finite time. II. Potentials for finite-time processes
Physical Review A, 1977Within the context of conventional time-independent thermodynamics, an algorithm is developed to construct potentials $\mathcal{P}$ that define the extremal values of work for processes with arbitrary constraints. An existence theorem is proved that demonstrates that such potentials $\mathcal{P}$ can be given for any quasistatic process.

Finite-time thermodynamics and thermodynamic length
Revue Générale de Thermique, 1996Abstract 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 ...

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 quantum thermodynamic processes
The European Physical Journal Special Topics, 2007We study a single quantum object subject to a parametrized distortion of its discrete spectrum and to a parametrized change of its state, which remains diagonal in its invariant energy eigenbasis. The Carnot and the Otto cycle are investigated in the quasistatic as well as in the dynamic (finite time) regime.

Finite-Time Thermodynamics and the Optimal Control of Chemical Syntheses [PDF]
Zeitschrift 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 ...

Finite-time thermodynamics. Active potentiostatting
Journal of Physics D: Applied Physics, 1998The paper addresses minimization of the dissipation in systems maintaining constant temperature or other constant intensive variables (potentiostatted systems). The entropy production and energy consumption of such systems are reduced from those of the traditional scheme if additional chambers are interposed between the system and its surroundings, in ...

Optimization in finite-reservoir finite-time thermodynamics
Physical Review E, 2014A 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.

Finite-time thermodynamics and the gas-liquid phase transition
Physical Review E, 2007In 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.
