Special Issue Information
Dear Colleagues,
Multiphase flow in turbomachinery represents a challenge for CFD modeling, particularly when simultaneous phenomena such as cavitation and sediment erosion are involved. In hydraulic turbines, although cavitation is a widely studied issue, important gaps remain, such as the accurate identification of cavitation zones. Classical correlations do not provide reliable predictions of these limits, especially in the transition between Francis and Kaplan turbines. The complexity increases further in sediment-laden scenarios, where solid particles interact with cavitation. In such cases, solid–fluid–vapor multiphase models become indispensable for identifying erosion zones. We encourage contributions that propose new cavitation formulations to improve CFD predictions, as well as the use of data-driven or CFD-AI approaches capable of enhancing predictive capabilities in complex scenarios. Contributions exploring the application of existing models under challenging conditions are also welcome. The CFD models should be supported by experimental validation to ensure reliability. Although motivated by hydraulic turbines, the scope extends to flow machines in general, involving cavitation and/or sediment erosion, opening opportunities for methodological advances that benefit a wide range of applications. We therefore invite the scientific community to contribute studies that advance the use of CFD in addressing 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. 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.
