The saturated and supercritical Stirling cycle thermodynamic heat engine cycle [PDF]

open access: yesAIP Advances, 2018
On the assumption that experimentally validated tabulated thermodynamic properties of saturated fluids published by the National Institute of Standards and Technology are accurate, a theoretical thermodynamic cycle can be demonstrated that produces a net-

Analytical Solution of Heat Transfer Performance of Grid Regenerator in Inverse Stirling Cycle [PDF]

open access: goldEnergies, 2022
The regenerator plays an extremely important role in the Stirling circulation. A grid regenerator can be used for inverse Stirling machines at room temperature due to its low flow resistance.

Studies on Stirling Power Cycles- A Review

open access: greenJournal of Advanced Mechanical Sciences, 2022
The Stirling power cycle consists of 2 isothermal processes (heat supply and heat removal processes) and two isochoric processes (compression and expansion processes).

Idealization of The Real Stirling Cycle

open access: yesJournal of Middle European Construction and Design of Cars, 2016
The paper presents a potential idealization of the real Stirling cycle. This idealization is performed by modifying the piston movement corresponding to the ideal Stirling cycle.

Endoreversible Stirling Cycles: Plasma Engines at Maximal Power [PDF]

open access: yesEntropy
Endoreversible engine cycles are a cornerstone of finite-time thermodynamics. We show that endoreversible Stirling engines operating with a one-component plasma as a working medium run at maximal power output with the Curzon–Ahlborn efficiency. As a main

Life cycle cost analysis (LCCA) of Stirling-cycle-based heat pumps vs. conventional boilers

open access: yesCleaner Environmental Systems, 2023
Heat pumps (HPs) which use low temperature (waste) heat and renewable energy sources to provide high temperature heat are widely regarded as a critical technology for reducing carbon dioxide emissions in the industrial sector.

Evaluation of the Environmental Sustainability of a Stirling Cycle-Based Heat Pump Using LCA

open access: yesEnergies, 2020
Heat pumps are increasingly seen as efficient and cost-effective heating systems also in industrial applications. They can drastically reduce the carbon footprint of heating by utilizing waste heat and renewable electricity.

Stirling Numbers of Forests and Cycles [PDF]

open access: diamondThe Electronic Journal of Combinatorics, 2013
For a graph $G$ and a positive integer $k$, the graphical Stirling number $S(G,k)$ is the number of partitions of the vertex set of $G$ into $k$ non-empty independent sets. Equivalently it is the number of proper colorings of $G$ that use exactly $k$ colors, with two colorings identified if they differ only on the names of the colors.

Magnetic Stirling Cycle for Qubits with Anisotropy near the Quantum Critical Point

open access: yesTechnologies, 2023
We studied the performance of a quantum magnetic Stirling cycle that uses a working substance composed of two entangled antiferromagnetic qubits (J) under the influence of an external magnetic field (Bz) and an uniaxial anisotropy field (K) along the ...

Numerical investigation of a new combined energy cycle based on Miller cycle, Organic Rankine cycle, Stirling engine and alkaline fuel cell

open access: yesEnergy Reports, 2021
Using a combined energy cycle based on conventional and/ or clean energy sources can be a suitable option to dominate the limitations in the field of energy. Meanwhile, the select of the prime power source in such processes is a challengeable issue.
