Effect of Finite-Size Heat Source's Heat Capacity on the Efficiency of Heat Engine. [PDF]

open access: yesEntropy (Basel), 2020
Heat engines used to output useful work have important practical significance, which, in general, operate between heat baths of infinite size and constant temperature.

The power of a critical heat engine. [PDF]

open access: yesNat Commun, 2016
Since its inception about two centuries ago thermodynamics has sparkled continuous interest and fundamental questions. According to the second law no heat engine can have an efficiency larger than Carnot’s efficiency.

A quantum heat engine driven by atomic collisions. [PDF]

open access: yesNat Commun, 2021
Quantum heat engines are subjected to quantum fluctuations related to their discrete energy spectra. Such fluctuations question the reliable operation of thermal machines in the quantum regime. Here, we realize an endoreversible quantum Otto cycle in the

Bound on Efficiency of Heat Engine from Uncertainty Relation Viewpoint. [PDF]

open access: yesEntropy (Basel), 2021
Quantum cycles in established heat engines can be modeled with various quantum systems as working substances. For example, a heat engine can be modeled with an infinite potential well as the working substance to determine the efficiency and work done ...

Solutions and Heat Engines [PDF]

open access: bronzeNature, 1929
IT is not usual for an author to complain of a review of his book; but I confess that the theory of osmotic pressure put forward (in place of an account of my own reasoning) by the reviewer, in NATURE of Feb. 16, of my book “Gases and Liquids”, almost took my breath away. As the reviewer's reply, in NATURE of Mar. 9, to Prof.

Isolated quantum heat engine [PDF]

open access: yesPhysical Review Letters, 2012
We present a theoretical and numerical analysis of a quantum system that is capable of functioning as a heat engine. This system could be realized experimentally using cold bosonic atoms confined to a double well potential that is created by splitting a ...

A sublimation heat engine. [PDF]

open access: yesNat Commun, 2015
AbstractHeat engines are based on the physical realization of a thermodynamic cycle, most famously the liquid–vapour Rankine cycle used for steam engines. Here we present a sublimation heat engine, which can convert temperature differences into mechanical work via the Leidenfrost effect.

Relativistic quantum heat engine from uncertainty relation standpoint. [PDF]

open access: yesSci Rep, 2019
Established heat engines in quantum regime can be modeled with various quantum systems as working substances. For example, in the non-relativistic case, we can model the heat engine using infinite potential well as a working substance to evaluate the ...

Optimizing the classical heat engine [PDF]

open access: yesPhysical Review Letters, 2000
A pair of systems at different temperatures is a classic environment for a heat engine, which produces work during the relaxation to a common equilibrium. It is generally believed that a direct interaction between the two systems will always decrease the
