Flow Visualization: Experiments and Techniques

Dear Colleagues,

Flow visualization is a technique used to observe and analyze the patterns and characteristics of fluid flow. It is a valuable tool in fluid mechanics research and engineering applications, as it allows researchers to gain insights into the behavior of fluids and identify various flow phenomena.

Flow visualization methods can be broadly categorized into two types:

1. Direct flow visualization: involves directly observing the flow using techniques such as dye injection, particle tracking, or smoke visualization;
2. Indirect flow visualization: involves using instruments and sensors to measure flow properties such as pressure, velocity, and temperature. These data are then processed to visualize the flow patterns and characteristics.

This Special Issue aims to gather recent advancements in the field of flow visualization techniques and present new findings in fluid mechanics using flow visualization techniques.

Suggested topics include, but are not limited to:

• Multiphase flow measurement and instrumentation;
• PIV/MicroPIV/Tomo-PIV/LIF-PIV techniques;
• High-speed photography;
• Experimental fluid mechanics;
• Measurements of a two-phase structure and dynamics of cavitation;
• Traditional and synchrotron X-ray imaging;
• Pressure-sensitive paint (PSP) technique;
• Multi-sensor data fusion;
• Pressure field reconstruction;
• AI techniques applied in experimental fluid mechanics.

We look forward to receiving your contributions, and hope this Special Issue will provide a platform for researchers to share their work and exchange knowledge and ideas.

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. Fluids 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 1800 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.
