Advanced Simulation and Experiment Methods of Flow Instability in Hydraulic Machinery

Dear Colleagues,

Flow instability is one of the most important research topics in the field of hydraulic machinery. Advanced numerical simulation and experiment methods are important means to study the unstable flow characteristics of hydraulic machinery. Recently, there has been a number of works showing the flow instability characteristics of hydraulic machinery based on advanced numerical simulation and experimentation methods. These unstable flows are mainly characterized by performance changes, pressure pulsations, secondary reflux, etc. The unstable flow may cause undesirable phenomena such as pulsation, unit vibration, severe performance degradation, etc. Advanced numerical simulation methods and experimentation methods allow us to learn more about the unstable flow mechanism inside hydraulic machinery.

This Special Issue on “Advanced Simulation and Experimentation Methods of Flow Instability in Hydraulic Machinery” seeks high-quality works focusing on the latest simulation and experiment technology for hydraulic machinery. Topics include but are not limited to:

• Flow instability phenomena in hydraulic machinery;
• Advanced simulation and experimentation methods of hydraulic machinery;
• Optimization design of pump;
• Research on the transition process of hydraulic machinery;

Internal flow mechanism of hydraulic machinery.

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.
