High-speed video recordings of metal powder pneumatic conveying in thin capillary pipes. Scientific Data, 12(1). https://doi.org/10.1038/S41597-025-04515-W10.1038/S41597-025-04515-Whttp://hdl.handle.net/20.500.14454/2531Many industrial processes require a consistent material flow in the form of powders, typically achieved through pneumatic conveying. This work presents a dataset of high-speed video recordings capturing the horizontal pneumatic conveying of metallic powders in thin capillary pipes. Additionally, pressure and photodiode recordings are included. The experimental setup is described in detail, with suggestions for potential improvements. In the video recordings, each particle is individually distinguishable and can be tracked across frameseng© The Author(s) 2025journal article2025-03-142052-4463
