In the installation, Sound of Bubbles, DO YOU FEEL STRESSED, rising bubbles in the water create sounds and form a calming and hypnotic soundscape that invites listeners to watch, listen and calm down. The sounds are picked up and amplified by underwater microphones. The stress-reducing installation makes playful use of the scientific phenomenon of "multiphase systems". In addition, detailed phenomena are brought closer in a playful way at a small experience corner.

Multiphase systems are ubiquitous in process engineering. The particle size plays a central role here, as it directly influences the mass transport, but also the hydrodynamics. At the Institute of Chemical Process Engineering, the focus is currently on three-phase bubble columns (gas/liquid+catalyst), such as those used in methanol synthesis. While conventional measurement techniques are used to detect the bubble size in two-phase systems, exciting starting points arise from the coupling of sound and artificial intelligence.

The project gives a first insight into the sound world of bubbles, which is relevant for further developments.
