Transport Processes in Single- and Multi-Phase Flow Systems

Dear Colleagues,

Transport processes that involve the transfer of mass, momentum and energy are fundamental to a variety of industrial systems and natural phenomena. These processes can occur with or without chemical reactions, and their behavior is influenced by the phase structure of the system, such as the single-phase or the multiphase flow environment. In single-phase transport systems, the processes are typically governed by diffusion, turbulence and heat transfer, etc.; however, in multiphase systems, such as particle laden flow or gas–liquid mixtures, interactions between the phases complicate transport and require the phase boundaries and the interphase exchanges to be considered. The introduction of chemical reactions further complicates these processes as they influence concentration gradients, the temperature field and properties of the fluid. In reactive single-phase flow systems, the transport equations are coupled with the homogeneous reaction kinetics. In multi-phase flow systems, the chemical reactions that occur at the phase interfaces can significantly influence mass transfer rates and momentum exchange, e.g., in catalytic reactions or the heterogeneous combustion of fuel. In addition to experimental and theoretical research, the development of computer models, such as CFD and machine learning models and methods, can be employed to better understand, analyze and optimize these transport processes, highlighting their applications in science and engineering.

This Special Issue, entitled “Transport Processes in Single- and Multi-Phase Flow Systems”, aims to collect novel research contributions that present experimental investigations, model transport processes, or provide comprehensive reviews that suggest research directions and reliable benchmarks for further investigations within this field.

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. Processes is an international peer-reviewed open access semimonthly 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.
