Regenerator Optimization for Stirling Cycle Refrigeration [PDF]

open access: yes, 1994
A cryogenic regenerator for a Stirling cycle is discussed using the gain in entropy per entropy transferred of a unit mass as the criterion of performance. Since the entropy of a unit mass (entropy times volume of a unit mass) remains constant in the transfer through an ideal regenerator, the fractional gain in entropy becomes a measure of the ...

Effects of different working gases on the heat transfer enhancement performance of a heating tube with spiral insert under oscillatory flow

open access: yesEnergy Reports, 2023
The working gas type had an important effect on the heat transfer performance of the turbulence device in the heater of Stirling engine, but the related researches were scarce, especially under the oscillatory flow.

Alternative thermodynamic cycle for the Stirling machine [PDF]

open access: yesAmerican Journal of Physics, 2017
We develop an alternative thermodynamic cycle for the Stirling machine, where the polytropic process plays a central role. Analytical expressions for pressure and temperatures of the working gas are obtained as a function of the volume and the parameter that characterizes the polytropic process.

Optimization of an irreversible Stirling regenerative cycle [PDF]

open access: yesJournal of Physics: Conference Series, 2015
In this work a Stirling regenerative cycle with some irreversibilities is analyzed. The analyzed irreversibilities are located at the heat exchangers. They receive a finite amount of heat and heat leakage occurs between both reservoirs. Using this model, power and the efficiency at maximum power are obtained.

Statistical generalization of regenerative bosonic and fermionic Stirling cycles [PDF]

open access: yesPhysical Review E, 2021
We have constructed a unified framework for generalizing the finite-time thermodynamic behavior of statistically distinct bosonic and fermionic Stirling cycles with regenerative characteristics. In our formalism, working fluid consisting of particles obeying Fermi-Dirac and Bose-Einstein statistics are treated under equal footing and modelled as a ...

Quantitative Stirling Cycle Measurements: P-V Diagram and Refrigeration [PDF]

open access: yesThe Physics Teacher, 2018
This paper describes simple modifications to a demonstration Stirling engine that allows one to make quantitative measurements of the Stirling cycle. First, we describe measurements of the $P$-$V$ diagram using an inexpensive pressure sensor and a common

A comparative study of open and closed heat-engines for small-scale CHP applications [PDF]

open access: yes, 2016
In this paper the authors compare and contrast open and closed-cycle heat engines. First of all, by way of example and to aid discussion, the performance of proprietary externally heated closed-cycle Stirling engines is compared with that of internally ...
