The position of the bubble is determined by an array of optical fibers and controlled [...] from rising gas bubbles under the influence of swarm turbulence with superimposed chemical reaction (DFG SPP 1740) The SPP 1740 aims to describe the mass transport of rising gas bubbles quantitatively, [...] is used to correlate and describe the mass transport of rising single bubbles. Furthermore, the data might be transferrable to bubble swarms. Publications from the project Helmers et al. (2022). Experiments

has been changed, and gas bubbles can be injected into the flow. Besides this investigation of the stability of this new channel, the scientists are interested in how the bubbles, formed by gas ingestion [...] needed. The general aim of the experiments is to shed light onto how fluids can be transported free of bubble formation with the aid of capillary channels. The experimental set-up on board the ISS is fitted [...] fluid flowing through it develops special flow profiles which can facilitate the removal of gas bubbles from the fluid by transporting them back to the surface.

In particular, the results should reveal which flow velocities can be achieved before bubbles are formed and the flow is [...] experiments are intended to shed light onto how capillary canals can help keep liquids free from bubble formation when they are transported in space. This is the start of a series of experiments lasting [...] transport it under conditions of microgravity, while at the same time preventing the formation of bubbles.
