Modeling, Simulation, and Reconstruction of 2-Reservoir Heat-to-Power Processes in Finite-Time Thermodynamics. [PDF]
Entropy (Basel), 2020 The connection between endoreversible models of Finite-Time Thermodynamics and the corresponding real running irreversible processes is investigated by introducing two concepts which complement each other: Simulation and Reconstruction.

Finite-Time Thermodynamics: Problems, Approaches, and Results. [PDF]
Entropy (Basel)In this manuscript, the typical problems of “finite-time thermodynamics”, their general methodology, and the general features of their solutions are considered. We also consider the role of minimal dissipation processes, the properties of the irreversibility index, and the consequences of its existence.

Future Perspectives of Finite-Time Thermodynamics. [PDF]
Entropy (Basel), 2022 Finite-time thermodynamics was created 45 years ago as a slight modification of classical thermodynamics, by adding the constraint that the process in question goes to completion within a finite length of time [...]

Finite-Time Thermodynamics in Economics. [PDF]
Entropy (Basel), 2020 In this paper, we consider optimal trading processes in economic systems. The analysis is based on accounting for irreversibility factors using the wealth function concept. The existence of the welfare function is proved, the concept of capital dissipation is introduced as a measure of the irreversibility of processes in the microeconomic system, and ...

Averaged Optimization and Finite-Time Thermodynamics. [PDF]
Entropy (Basel), 2020 The paper considers typical extremum problems that contain mean values of control variables or some functions of these variables. Relationships between such problems and cyclic modes of dynamical systems are explained and optimality conditions for these modes are found.

Optimal finite-time processes in stochastic thermodynamics [PDF]
Physical Review Letters, 2007 For a small system like a colloidal particle or a single biomolecule embedded in a heat bath, the optimal protocol of an external control parameter minimizes the mean work required to drive the system from one given equilibrium state to another in a ...

Linking Optimization Success and Stability of Finite-Time Thermodynamics Heat Engines. [PDF]
Entropy (Basel)In celebration of 50 years of the endoreversible Carnot-like heat engine, this work aims to link the thermodynamic success of the irreversible Carnot-like heat engine with the stability dynamics of the engine.

The First Fifty Years of Finite-Time Thermodynamics. [PDF]
Entropy (Basel)The year 1975 marked the beginning of an entirely new direction for thermodynamics with the publication of Curzon and Ahlborn’s innocent-looking short paper “Efficiency of a Carnot engine at maximum power output” [...]

Quantum Finite-Time Thermodynamics: Insight from a Single Qubit Engine. [PDF]
Entropy (Basel), 2020 Incorporating time into thermodynamics allows for addressing the tradeoff between efficiency and power. A qubit engine serves as a toy model in order to study this tradeoff from first principles, based on the quantum theory of open systems.
