Advanced Computational Fluid Dynamics (CFD) and Heat Transfer Studies on Cryogenic Flow and Its Systems

Dear Colleagues,

Computational fluid dynamics and heat transfer are important both in industrial and scientific communities, especially in aeronautics, astronautics, and motor vehicles, as well as energy system design. Due to the high specific impulse, low-emissions, and environmental friendliness, cryogenic fluids are shown to be widely used in both aerospace engineering and motor vehicles, as well as advanced green energy systems.

As the cryogenic fluids are sensitive to heat transfer, which may trigger two-phase flows, boiling, as well as many complex multiphysical coupled dynamics, massive usage of cryogenic fluids confronts many scientific and technological problems, including both storage, transport, and utilization. Presently, it has become obvious that a closer understanding of the relationship between fluid dynamics and heat transfer for cryogenic fluids is vitally necessary. Due to the high costs of cryogenic fluid experiments, numerical simulations and validations are feasible. Today, the main objectives are the improvement of numerical methods for coupled fluid dynamics and heat transfer, optimization design of thermal management, and performance validation of cryogenic propulsion, transportation, and energy systems.

The present Special Issue of Energies aims to gather innovative research and the latest developments in cryogenic computational fluid dynamics (CFD) and heat transfer. More specifically, topics of interest for the Special Issue include (but are not limited to):

• Numerical methods and simulations of two-phase flow and phase change heat transfer in cryogenic fluids.
• Cryogenic fluid storage, transport, measurement technologies for aeronautical, astronautical, and ground vehicles. Advanced green propulsion, ground transportation, energy system conceptual design based on cryogenic fluid dynamics.
• Thermal management, fluid-thermal-structure coupling analysis for advanced electro-mechanical actuation systems.

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. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
