Special Issue Information
Dear Colleagues,
Gas–liquid reactors (bubble columns, agitators, airlift reactors, etc.) are the most frequently used units in the chemical industry (absorption, oxidation, chlorination, etc.). They are also used in wastewater treatment, flotation, methanol synthesis, Fischer–Tropsch synthesis, papermaking, etc. Over the past four decades, the classical topics of hydrodynamics, mixing, mass transfer (MT) and heat transfer in these reactors have been extensively studied. Many new empirical and theoretical correlations have been developed. The presence of catalytic particles has also been studied. However, new areas of research in these types of reactors have emerged. The most important new areas are the Computational Fluid Dynamics (CFD) simulations and the operation with various ionic liquids, as well as the new modifications (including vibrations) of these classical reactors. This Special Issue will be especially dedicated to these topics, but many other new applications will also be considered. The process of MT with a chemical reaction should also be investigated. It is of key importance to develop new and reliable measurement techniques for more accurate estimation of both the local bubble diameters and local gas holdups. New concepts for a better characterization of the liquid turbulence in gas–liquid reactors are also needed. It is especially important to have new visualization techniques in order to study the eddy lengths and bubble wakes. Their size and movement is important for MT enhancement. Contributions focused on these topics are welcome in this Special Issue.

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. Fluids 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 1800 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.
