Efficiency at maximum power of low dissipation Carnot engines [PDF]
, 2010 We study the efficiency at maximum power, $\eta^*$, of engines performing finite-time Carnot cycles between a hot and a cold reservoir at temperatures $T_h$ and $T_c$, respectively.

Three-State Quantum Heat Engine Based on Carnot Cycle
Jurnal Fisika Unand, 2020 In this paper,we consider three models of quantum heat engines based on Carnot cycle using three energy levels; (1) the ground state, (2) the degenerate state, and (3) the highest energy state.

Metal Consumption of Heat Engines and Heat Capacity of their Working Fluids [PDF]
Problems of the Regional Energetics, 2020 Ensuring efficient energy supply in general and heat supply in particular together with creation of air conditioning systems is a very urgent task of modern energy industry, particularly acute in the absence of large centralized energy sources.

Quantum heat engines with Carnot efficiency at maximum power
Physical Review Research, 2022 Heat engines constitute the major building blocks of modern technologies. However, conventional heat engines with higher power yield lesser efficiency and vice versa and respect various power-efficiency trade-off relations.

Double Contour Thermodynamic Cycle with Unidirectional Heat Transfer between the Refrigeration and the Energy Cycle [PDF]
Problems of the Regional Energetics, 2019 Practical characteristics of the method for improving cycles of complex cooling thermotrans-formers associated with the regeneration of the refrigeration cycle heat productivity (RCHP) are considered. The use of heat from the working fluid compression in

Molecular kinetic analysis of a local equilibrium Carnot cycle. [PDF]
Physical Review E, 2016 We identify a velocity distribution function of ideal gas particles that is compatible with the local equilibrium assumption and the fundamental thermodynamic relation satisfying the endoreversibility.

Fourier Heat Conduction as a phenomenon described within the scope of the Second Law
, 2014 The historical development of the Carnot cycle necessitated the construction of isothermal and adiabatic pathways within the cycle that were also mechanically "reversible" which lead eventually to the Kelvin-Clausius development of the entropy function ...

Efficiency at maximum power of minimally nonlinear irreversible heat engines [PDF]
, 2012 We propose the minimally nonlinear irreversible heat engine as a new general theoretical model to study the efficiency at the maximum power $\eta^*$ of heat engines operating between the hot heat reservoir at the temperature $T_h$ and the cold one at ...
