Special Issue Information

Dear Colleagues,

The Guest Editors of the MDPI Energies Special Issue “Heat Transfer in Stirling Engines” are inviting submissions for publication. Stirling engines have many applications, ranging from sustainability-oriented devices to high-tech apparatuses alike. In every case, the thermal behavior of the engines is of paramount importance, and research in this field has seen many emerging models and technologies in recent years. In this Special Issue, all aspects of Stirling engines will be addressed, with a focus on heat transfer, thermodynamics and fluid mechanics. In addition, research on engine components is also of interest, such as the modelling or simulation of regenerators, heaters, coolers, or types of pistons.

The topics of interest for this Special Issue include, but are not limited to:

  • Stirling engine thermal and fluid mechanics modelling;
  • Modelling and simulation of 1D and 3D Stirling designs;
  • Numerical solution methods for engine design;
  • Heat transfer in Stirling engines;
  • Different types of Stirling engines (alpha, beta, gamma);
  • Free-piston Stirling engines;
  • Differentiated engines based on the Stirling cycle (Vuilleumier engines, conjoined Stirling engines etc.);
  • Cryogenic applications of Stirling engines (i.e., used for the liquefaction of gases, superfluid Stirling refrigerators etc.);
  • Solar Stirling engines;
  • Special purpose Stirling engines;
  • Applications in renewables and sustainability (Stirling heat pumps, use of Stirling coolers in carbon capture etc.).

In this Special Issue authors may also submit review papers considering the modelling and heat transfer of Stirling engines. Considering the review papers, authors are encouraged to first contact the Editors to verify that the proposed review is of interest to the Issue.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

This paper presents a parametric analysis of a β-type Stirling engine, focusing on the impact of various rotational speeds. The investigation employs a three-dimensional computational fluid analysis model. The study places emphasis on monitoring and understanding the temperature variations across the primary components of the engine, including the regenerator, heater, and cooler. The full apparatus is designed and simulated, acquiring the results for its energy output and thermal behavior.Using this CFD model, parameterization optimization is presented, aiming to establish the best conditions for the engine and regenerator efficiencies. Utilizing the results of the behavior of the machine, a correlation between the Nusselt and Reynolds numbers with regard to the rotational speeds is produced, giving a further understanding of the conduct of the working medium in the system.
