LIQUIDS (SODI-IVIDIL)
Research Area: Fluid Physics
Expedition(s): 19- 22
Principle Investigator(s): ● Valentina Shevtsova, University of Brussels, Brussels, Belgium
RESEARCH OBJECTIVES
The Selectable Optical Diagnostics Instrument - Influence of VIbrations on DIffusion of Liquids
(SODI-IVIDIL) investigation studies the influence of controlled vibrations on diffusion in liquids
in the absence of buoyant convection (transfer of heat by movement) in microgravity. These
studies represent part of a series of investigations on the International Space Station (ISS) on
how heat and particles move through liquids in microgravity. SODI-IVIDIL investigates the
effects of residual vibrations (g-jitter) on experiments involving diffusion in liquids. Researchers
plan to characterize the spectral influence of g-jitter to
increase the understanding of the kinetic mechanisms
influencing diffusion effects in the presence of vibrations,
therefore allowing for more successful science to be
operated aboard ISS.
EARTH BENEFITS
Based on previous studies, scientists have developed
numerical simulations to help understand oil behaviors in a
drilled well. The SODI-IVIDIL experiment allows scientists to
confirm and refine the parameters of their models, leading
to more accurate predictions about oil wells being
considered for extraction. This investigation also data for
applications to fields in mineralogy and geophysics for
predictions about the locations of natural resources
beneath the Earth's surface.
