This year’s edition ISUD2023 was organised by the University of Kobe. It was a very nice opportunity to discover the latest applications of Ultrasonic Doppler methods.

An enthusiastic keynote was given by Prof. Erich Windhab, with presentation of viscosity measurements by Ubertone's UB-Lab UVP (Ultrasonic Velocity Profiler), done at ETH Zürich’s Food Processing Lab, by Dr Kim Mishra and Dr Damien Dufour. Coupling of in-line UVPPD rheometry and USDMA for process control in polymorph crystallization processing of chocolate confectionery masses by E. Windhab, K. Mishra and L. Grob.

The Power and Energy Lab of TUMSAT (Tokyo University of Marine Science and Technology) presented measurements from their deployment of a Peacock UVP from Ubertone in deep sea, at -1300 m! Investigation of the influence of the background ocean current on flow measurements using the UVP method by S. Ueno and T. Ihara.

Prof. Yuji Tasaka, from Hokkaido University, presented his results obtained with the UB-Lab P, following the UVP springboard call for projects. They did "adopt UB-Lab P, a palm-size portable UVP as the new generation of UVP provided by Ubertone, as the velocity profiler of USR for future development of tabletop USR.", a citation from his paper Applications of ultrasonic spinning rheometry by Y. Tasaka, K. Ohie, H. Chin, A. Takano, T. Yoshida and Y. Murai.

Stéphane Fischer, founder of Ubertone presented Noémie Fritsch’s work with the UB-Lab 3C field prototype: Sediment dynamics by bistatic ultrasonic Doppler under real waves by N. Fritsch, G. Fromant, F. Floc'h, S. Fischer, Y. Cobac, C. Poitou, C. Prunier, S. Bertin, E. Augereau, M. Jaud and J. Tanrin.

Complementing the presentations, discussions were possible at Ubertone’s booth. We were happy to hold this booth with our local distributor FlowTech Research.

In this very open-minded mood, we did some measurements with our UB-Lab P, on the neighbourhood booth setup, an educational Taylor-Couette setup by FlowBiz.

As for every ISUD edition, the Ubertone Student Award was a nice motivation for students to present their work in this field. Discover here the awarded winners!

Preceded by a short cruise on the Gozabune Atakemaru, the Met-Flow dinner took place at a local sake brewery, Syushinkan and was accompanied by music: piano, song and saxophone, by Prof. Takeda, Prof. Windhab and Mr Mariette.

The next ISUD 2025 edition was announced. It will be held in Grenoble, France, organised by the LEGI (Laboratoire des Écoulements Géophysiques et Industriels), co-organised by EPFL and Ubertone.
