Entropy, Carnot Cycle and Information Theory, Part 2 [PDF]

open access: goldEntropy
This second part of this companion paper the Carnot cycle is analyzed trying to investigate the similarities and differences between a framework related to thermodynamics and one related to information theory. The parametric Schrodinger equations are the

Economic Cycles of Carnot Type [PDF]

open access: yesEntropy, 2021
Originally, the Carnot cycle was a theoretical thermodynamic cycle that provided an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work, or conversely, the efficiency of a ...

Maximum power, ecological function and efficiency of an irreversible Carnot cycle: a cost and effectiveness optimization [PDF]

open access: gold, 2008
In this work we include, for the Carnot cycle, irreversibilities of linear finite rate of heat transferences between the heat engine and its reservoirs, heat leak between the reservoirs and internal dissipations of the working fluid. A first optimization

Optimal Heat Exchanger Area Distribution and Low-Temperature Heat Sink Temperature for Power Optimization of an Endoreversible Space Carnot Cycle [PDF]

open access: yesEntropy (Basel), 2021
Using finite-time thermodynamics, a model of an endoreversible Carnot cycle for a space power plant is established in this paper. The expressions of the cycle power output and thermal efficiency are derived.

Quantum Carnot cycle with inner friction [PDF]

open access: yesQuantum Information Processing, 2020
A single driven spin is investigated as the working substance of a six-stroke irreversible quantum Carnot cycle. The role of inner friction associated with the finite-time adiabatic transformations on the cycle efficiency and the harvested work are ...

Hierarchical equations of motion for multiple baths (HEOM-MB) and their application to Carnot cycle [PDF]

open access: greenJournal of Chemical Physics
We have developed a computer code for the thermodynamic hierarchical equations of motion derived from a spin subsystem coupled to multiple Drude baths at different temperatures, which are connected to or disconnected from the subsystem as a function of ...

Quantum thermodynamic Carnot and Otto-like cycles for a two-level system [PDF]

open access: green, 2012
From the thermodynamic equilibrium properties of a two-level system with variable energy-level gap $\Delta$, and a careful distinction between the Gibbs relation $dE = T dS + (E/\Delta) d\Delta$ and the energy balance equation $dE = \delta Q^\leftarrow -

Performance Analysis and Optimization for Irreversible Combined Carnot Heat Engine Working with Ideal Quantum Gases

open access: yesEntropy, 2021
An irreversible combined Carnot cycle model using ideal quantum gases as a working medium was studied by using finite-time thermodynamics. The combined cycle consisted of two Carnot sub-cycles in a cascade mode.

Nonlinear Thermodynamic Analysis and Optimization of a Carnot Engine Cycle [PDF]

open access: goldEntropy, 2016
As part of the efforts to unify the various branches of Irreversible Thermodynamics, the proposed work reconsiders the approach of the Carnot engine taking into account the finite physical dimensions (heat transfer conductances) and the finite speed of ...
