Computational Fluid Dynamics (CFD) Simulations for Fusion Reactors

Dear Colleagues,

It is widely recognized that the development of energy from nuclear fusion is entering a new era. The ITER experiment should start operating in this decade, and various efforts are quickly proceeding to the design of a demonstration fusion reactor, expected to show the production of electricity in the second half of the century. Additionally, energy companies are starting to consider nuclear fusion as a goal close enough to attract private investors. In short, we are in the process of transforming a purely scientific process into a mixed scientific/economical project with exciting development perspectives.

In this framework, it will be critical to develop computational tools including the most advanced scientific knowledge and, at the same time, compliant with industry-standard software quality criteria. Such a process is currently starting. We hope that this Special Issue will help to bring together experiences and points of view on the development of CFD software for the upcoming generation of fusion devices, and to stimulate constructive discussion and collaboration among researchers in the field. The issue will focus on the following topics:

• Turbulence models in CFD codes for fusion applications;
• Software quality assurance in CFD codes in the fusion community;
• Validation of fusion computational models and benchmark with experimental data;
• Application of artificial intelligence techniques in connection with CFD software;
• Inter-relation with non-standard CFD techniques (Monte Carlo, particle in cell, gyro-kinetic, etc.);
• Prediction of a fusion reactor environment: what can be done and what is still missing.

Authors are invited and welcome to submit original research papers, reviews, and short communications.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes 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 2400 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.
