Special Issue Information

Dear Colleagues,

Cryogenic fluids, including liquid nitrogen, liquid oxygen, liquid hydrogen, liquid helium, etc, are experiencing rapid growth in industrial applications, aerospace missions, and large scientific apparatuses. Owing to us living in a normal temperature environment, an evitable temperature decrease process will be experienced by the cryogenic facilities or by the transferring pipeline prior to them contacting the cryogenic fluids, and this process is usually defined as “cryogenic quenching” or “cryogenic chilldown”. For example, for a cryogenic propellant loading to rocket, the transferring pipeline must firstly be cooled down to the propellant temperature, after which fast propellant fueling can be executed. In a typical quenching operation, complex thermophysical evolutions could occur simultaneously, involving liquid-vapor phase change, two-phase flow pattern change, boiling mechanism evolution, thermophysical property variation, and so forth. To reach a fast-quenching purpose, the detailed two-phase flow properties inside the pipeline and the interior heat transfer mechanisms should be theoretically and experimentally investigated, and thus a new quenching scheme or technique could be proposed to accelerate the temperature decrease rate.

It is hoped that this Special Issue could be a forum for the presentation of new and improved quenching techniques for the cryogenic fluid filling system, as well as provide a fundamental understanding of the heat transfer mechanism for cryogenic fluids.

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. Entropy is an international peer-reviewed open access monthly 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.
