The RUBI Experience is travelling to the International Space Station

RUBI Experience (Reference mUltiscale experiment for Boiling Investigation) will be launched on the International Space Station on July 21, 2019 and operated in the Fluid Science Laboratory for a duration of 5 months. It is the next step for this project supported by European Space Agency in which a team from Institut de Mécanique des Fluides de Toulouse (CNRS / Toulouse INP / UT3) has been working in collaboration with a dozen other European teams, since 2005.


RUBI Experience

RUBI Reference experiment for mUltiscale Boiling Investigation concept has been defined jointly by  Darmstadt University, University of Pise,  Aix - Marseille University, Université Libre de Bruxelles, EPFL Lausanne, IMFT and other international partners.


The objective of this experiment is to study the growth and the detachment of an isolated bubble and the heat and mass transfers at the bubble foot for various wall superheating, liquid subcoolings and potentially in an electric field or in a shear flow.

IMFT involvement

IMFT is particularly involved in studying the growth and detachment of a bubble in a shear flow. Several laboratory preparatory and microgravity experiments during parabolic flights have been conducted over the last 10 years. These bubble-scale experiments are intended to improve the modelling of boiling heat transfer in complex two-phase systems as for example in the thermal control of electronic components in satellites or in space propulsion.
