Cryogenic Flows

Dear Colleagues,

The importance of cryogenic technology in modern society continuously increases, enabling advances in medical, energy, space, defense, computing, and transportation industries. Cryogens are used as working fluids in many systems, whereas hydrogen is also employed as a high-performing fuel. To design cryogenic fluid systems with confidence, a good understanding of cryogenic flows is required. Properties of cryogens are very different from conventional normal-temperature fluids and sometimes include quantum effects. Liquid cryogens are often kept at temperatures close to their saturation values, which easily leads to fluid evaporation due to a pressure drop in the flow or heat addition through the pipe wall. Significant fluid expansion due to phase change complicates flow patterns and often leads to instabilities. This makes prediction of cryogenic flow regimes rather difficult, while experimental measurements of flow characteristics at such low temperatures are very challenging.

To increase confidence in the design of cryogenic systems and decrease their costs, more comprehensive information on cryogenic flows is required. This Special Issue invites papers on both experimental and modeling studies furthering understanding of cryogenic flow phenomena. The topics include (but are not limited to) properties of cryogenic fluids, ortho-parahydrogen conversion, different flow regimes, multiphase phenomena, flow instabilities, cryogenic heat transfer, fluid system components (pumps, valves, etc.), and novel measuring techniques for cryogenic flows.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cryo is an international peer-reviewed open access quarterly 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 1000 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.
