SODI-Particle Vibration
The objective of Particle Vibration was to study the formation of structures when a liquid with suspended particles is subjected to vibrations and specific temperature conditions. These structures result from the accumulation of particles due to thermo-vibrational convection in microgravity.

The experiment involves several key elements and individuals. It is a SODI experiment, installed in the Microgravity Science Glovebox (MSG)on the International Space Station (ISS). The experiment is led by the UK Space Agency, with Marcello Lappa serving as the principal investigator from the University of Strathclyde in Glasgow. The E-USOC, as a delegated center of the European Space Agency (ESA), plays a crucial role in preparing, operating, and supporting the execution of the experiment.
SODI, which stands for Selectable Optical Diagnostics Instrument, is a modular instrument designed for conducting experiments related to fluid mechanics in the microgravity environment of space. One of the key advantages of SODI is its adaptability and versatility. The instrument can be reconfigured and modified to accommodate a wide range of experiments and research objectives. Over the years, SODI has been utilized for multiple experiments, including studies on diffusion, thermovibrational convection, and the behavior of multi-phase liquids.

Experiment description
The Particle Vibration experiment focuses on studying the formation of various structures in liquid suspensions under specific temperature and vibration conditions. By subjecting the suspensions to controlled vibrations and applying varying temperature gradients, the experiment aims to investigate the effects of thermal and vibrational forces on particle behaviour. These forces can lead to the accumulation and rearrangement of particles, resulting in the formation of distinct structures (see simulated examples below). The experiment takes advantage of the unique microgravity environment provided by the ISS to observe and analyze these phenomena without the interference of gravitational forces. By understanding how temperature and vibration influence the formation of structures in liquid suspensions, the experiment contributes to our knowledge of fluid mechanics and has potential implications in fields such as materials science and industrial processes.
