The #Scilight journal from the American Institute of Physics just featured an article authored by our researchers. Read it here! The study led by C. Peromingo, P. Salgado Sánchez, D. Gligor, A. Bello, and J. Rodríguez, published in Physics of Fluids (2023), addresses innovative methods to reduce sloshing in microgravity environments. Simulations were conducted to identify the optimal shape, number, and arrangement of baffles in a rectangular tank. Additionally, temperature modulation was introduced to counteract the original sloshing motion. Findings: The findings demonstrated that the ideal combination of baffles and temperature modulation reduced sloshing decay time by over 80%. This strategy showed significant ...

After a year of intense work, both teams from E-USOC have come back with a big amount of promising results and a magnificent experience. “We are really satisfied with the work done and, despite of last minute problems and some unexpected surprises, we are pleased with the outcomes”, both teams asseverate. Images from the parabolic flights. Source: NoveSpace Convection, a well-known phenomenon on Earth and used in several applications, disappears in weightless environments. In this sense, the solid-liquid interface of a system evolves in a larger timescale and thus, it complicates heat evacuation. In the presence of a free surface, however, a ...

SODI-DCMIX experiment continues with a new science campaign. SODI was comfortably stowed in Columbus while other experiments did their duties in MSG and now it is SODI´s time again! Astronaut Kate Rubins (#AstroKate) brought SODI and DCMIX cells back from their inactivity and started the installation. After an almost 3 hour set up activity, Kate managed to put all things together and woke SODI up again. Silent space radiation could have damaged SODI software during its rest and that´s why USB recovery was prepared and launched to the Station on 18 July. However, this was not the case since SODI started ...

The SODI-DCMIX2 experiment aims to study the diffusion coefficients of ternary fluid mixtures samples in a microgravity environment. In specific, in different petroleum field samples and refine petroleum reservoir models, to help lead to more efficient extraction of oil resources. Development and validation of the on-board procedures and automatic scripts, planning of the on-board activities, remote control and monitoring of the payload, troubleshooting of anomalies in a quick and agile way, data retrieval and dissemination to the scientific community, have been some of the tasks carried on by E-USOC in this project, for which there has been a tight coordination and collaboration ...

After 13 months of continuous operations and more than 260 GB of science data generated, science campaign for GeoFlow-2 can be considered a huge success, overpassing all expectative and giving more results than initially expected. GeoFlow-2 objective was to generate further results to check and improve numeric models of the Earth mantle. That information complements the results obtained by geological phenomena numeric simulators, confirming or ameliorating their conclusions. The experiment has investigated the flow of an incompressible viscous fluid (alkanol 1-Nonanol) held between two concentric spheres. A central force field was introduced by applying a high voltage difference ...
