State-of the-Art, Challenges and Perspectives in Hydraulic Machines and Systems

Dear Colleagues,

Modern hydraulic machines and systems are now facing new challenges associated with the variable demand on the energy market as well as limited energy storage capabilities. A great flexibility is required in operation over an extended range of regimes far from the best efficiency point. As a result, unsteady and transient phenomena occur in the operation of hydraulic machines and systems, diminishing their lifetime. The research topics in this Special Issue focus on: (i) the theoretical, numerical, and experimental investigations associated to the unsteady and transient phenomena developed in hydraulic machines, equipment, and systems, (ii) single-, two-, and multiphase phenomena in hydraulic machines and systems, (iii) innovative technologies and new concepts in hydraulic machines and systems to assess and to extend their lifetime, and (iv) passive, semiactive, and active control techniques applied to hydraulic machines to improve their performances.

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. Energies 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.
