Special Issue Information
Dear Colleagues,
Axial flow turbines are critical components in gas and steam turbine engines, where efficiency, reliability, and performance are paramount. This Special Issue focuses on recent advances in controlling flow phenomena within axial turbines, aiming to enhance their aerodynamic performance under varying operational conditions. Key challenges include managing secondary flows, boundary layer separation, tip leakage and wake mixing—factors that significantly contribute to aerodynamic losses. Emerging flow control techniques, both passive (e.g., end wall contouring, fillets, and vortex generators) and active (e.g., synthetic jets and pulsed blowing), offer promising solutions to mitigate these losses and improve turbine stage efficiency. The integration of accurate low-, mid-, and high-fidelity computational studies, experimental studies, and machine learning approaches enables deeper insight into flow behavior and control strategies. Contributions are invited that explore novel methodologies, validate control techniques, or present design optimizations that lead to improved flow uniformity, reduced losses, and enhanced overall turbine performance. This Issue aims to bridge the gap between fundamental research and practical implementation in industrial axial turbine design.

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. Machines 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.
