Special Issue Information
Dear Colleagues,
With the increasing frequency of space activities, efficient thermal management needs to be addressed. Phase change heat transfer is widely used as an efficient method for transferring heat. For example, in pool boiling, gravity drives bubbles away from the heating wall in the Earth’s environment, and fresh liquid is added to maintain phase transformation heat. Under the action of super gravity, the detachment frequency of bubbles is accelerated, and phase transformation heat is enhanced. In microgravity, due to the substantial reduction in gravity, it is difficult for bubbles to leave the heating surface. However, the prediction model of boiling on the ground (such as the Rohsenow relation of boiling in a nuclear state pool) has a large error in variable gravity conditions. Thus, we need more research on boiling under changing gravity conditions.
In this Special Issue, we want to report on the boiling, condensation, melting, and solidification phase change heat transfer mechanisms under shifting gravity conditions, including heat transfer characteristics under microgravity, bubble dynamics, two-phase flow pattern and pressure drop, variable gravity phase change heat transfer prediction model, and numerical simulation technology.

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. Aerospace 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 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.
