Studying Liquid Behavior In Microgravity

Observing liquid behavior inside a sphere in microgravity provides a good model for what happens in a spacecraft’s fuel tank.

FLUIDICS, an investigation from ESA, evaluates the behavior of liquid in a sphere, including sloshing and wave turbulence. Results could provide insight into measuring the volume of the liquid, which may help improve the guidance and precision of satellites and optimize their lifespan through better fuel management.

This investigation also may help provide a better understanding of Earth’s oceans, including the phenomenon of “rogue waves,” and contribute to improving climate prediction systems and optimizing the use of ocean-based renewable energy. Crew members performed several runs of the experiment during the week.
