Flow and Heat Transfer in Gas-Cooled Nuclear Reactors

Dear Colleague,

Gas-cooled reactors have promising applications in electricity generation, cogeneration, and industrial process heat. Two of six Gen IV nuclear systems candidates are gas-cooled reactors, i.e., very high-temperature reactors and gas-cooled fast reactors. Smaller-scale gas-cooled reactors can be deployed in remote areas or in space as electricity or power suppliers.

Gas flow and heat transfer are fundamental to the thermal hydraulic design and safety analysis of gas-cooled reactors. New gas coolants, such as helium–xenon mixtures and supercritical carbon dioxide, need to be investigated for their thermal properties, as do turbulence models in novel gas-cooled nuclear systems. The complex geometries of reactor cores make it difficult to identify flow and heat transfer features. High-temperature operation conditions highlight the effect of thermal radiation, combined with conduction and convection, in gas flow and heat transfer. A deeper understanding of gas flow and heat transfer is necessary in order to promote gas-cooled nuclear reactors among designers, regulators, and investors.

We invite academics and researchers to submit their original and unpublished manuscripts to this Special Issue. Topics suitable for this Special Issue include, but are not limited to:

• Thermal hydraulic analyses in high temperature gas-cooled reactors;
• Thermal hydraulic analyses in gas-cooled micro/space reactors;
• Modeling, simulations, or experiments of gas flow and heat transfer in nuclear energy systems;
• Advances in fundamentals of gas flow and heat transfer.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. 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). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
