Construction of a quantum Stirling engine cycle tuned by dynamic-angle spinning [PDF]

open access: yesPhysica Scripta, 2023
In this contribution, we investigate two coupled spins as a working substance of the quantum Stirling heat engine cycle. We propose an experimentally implementable scheme in which the cycle is driven by tuning the dipole-dipole interaction angle via a ...

A Comprehensive Perspective of Waste Heat Recovery Potential from Solar Stirling Engines [PDF]

open access: yesE3S Web of Conferences, 2021
Despite the higher efficiency advantage, the cost reduction of PV technology has been more successful compared to the dish Stirling engine (DSE) due to the large market volume and sturdy competition.

A Potential Method to Predict Performance of Positive Stirling Cycles Based on Reverse Ones

open access: yesEnergies, 2021
There are two kinds of working mechanisms for the Stirling cycle, i.e., the positive and the reverse cycles, and a Stirling engine (SE) can be operated as a Stirling refrigerator (SR).

Analytical model for Stirling cycle machine design [PDF]

open access: yesEnergy Conversion and Management, 2010
In order to study further the promising free piston Stirling engine architecture, there is a need of an analytical thermodynamic model which could be used in a dynamical analysis for preliminary design. To aim at more realistic values, the models have to take into account the heat losses and irreversibilities on the engine.

Efficiency Reduction in Stirling Engines Resulting from Sinusoidal Motion

open access: yesEnergies, 2018
Stirling engines have a high potential to produce renewable energy due to their ability to use a wide range of sustainable heat sources, such as concentrated solar thermal power and biomass, and also due to their high theoretical efficiencies.

Stirling Numbers of Uniform Trees and Related Computational Experiments

open access: yesAlgorithms, 2023
The Stirling numbers for graphs provide a combinatorial interpretation of the number of cycle covers in a given graph. The problem of generating all cycle covers or enumerating these quantities on general graphs is computationally intractable, but recent

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.

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 ...
