Workshop on Ultrasonic Doppler for Hydraulics in laboratory flumes

This Workshop on Ultrasonic Doppler (WUD) edition for hydraulics in laboratory flumes is organised by the Karlsruhe University of Applied Science (HKA) in Germany together with nearby Ubertone in Strasbourg, France. It will take place from lunch to lunch on June 14-15th, 2022 at the hydraulic laboratory of the HKA. The goal of this workshop is to give the opportunity to Master Students and PhD candidates to discover, use and discuss with peers about Ultrasonic Doppler Methods for Fluid Mechanics and Fluid Engineering.

The content of the workshop will be centered on experimental practice, including exercises of installation, data recording and data processing of UVP (Ultrasonic Velocity Profiler) and ADVP (Acoustic Doppler Velocity Profiler) on two laboratory flumes.

A part of the workshop will also be dedicated to peer-to-peer discussions, to discuss measurement needs, methods and applicability of the methods. Therefore, ongoing related projects of participants can briefly be presented (max. 5min) followed by discussions among experienced and new users (participants).

Theoretical and lecture-like information will be sent in advance, for the student to read and study beforehand.

On a lunch-to-lunch basis, this event is free of charge for the participants, except for the lunches and accommodation, which has to be taken care of by the participants themselves. As an ice-breaker, we invite the participants to have lunch together on the first day at the university canteen at 12:00 am.

Coffee breaks during the workshop and dinner on June 14th will be organised and offered.

Exercises topics:

  • Ultrasonic Doppler measurement technique
  • Ultrasonic Velocity profiler
  • Acoustic Doppler Velocity profiler
  • Monostatic and bistatic measurement technique
  • Open channel flumes
  • Acoustic scatterers for quality data
  • Through-wall measurements
  • Turbulence measurement
  • Bed roughness influence
