Numerical Modeling and Simulation of Multi-Phase Flows

Dear Colleagues,

Multi-phase flows are characterized by two or more material interfaces, including those between continuous and dispersed phases of water, air and solid. Two typical flows can be identified—disperse flows and separated flows—the former being those consisting of finite particles, water drops, or air bubbles distributed within a continuous phase. The latter is defined as consisting of two or more continuous streams of immiscible phase, such as water and air, separated by interfaces. Multiphase flow behaviors are highly influenced by the complex interactions at material interfaces.

Multi-phase flows can be described with governing equations in Eulerian–Eulerian, Eulerian–Lagrangian, or Lagrangian–Lagrangian form. Due to the presence of material interfaces and the associated complex interactions, the numerical modeling and simulation faces many challenges compared with that of traditional hydrodynamics, such as the accurate presentation and transport of material interfaces, physically sound interface interaction, reliable solutions for complex hydrodynamic problems, and high-performance computing. This Special Issue aims to address different aspects of these challenges.

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. Water 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 2600 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.
