Samples Liege foam in microgravity during the mission Oasiss

Among the various experiments to be conducted during the mission Oasis, one is from Liege to study the behavior of foam in microgravity conditions. The experience is to lather on board the Columbus module, five plates, each containing a dozen liquid samples.
The project entitled "Foam Stability" was designed and prepared in the Department of Physics, University of Liege in the research laboratory GRASP (Group for Research & Applications in Statistical Physics).

Among the various experiments to be conducted during the mission Oasis, one is from Liege to study the behavior of foam in microgravity conditions. The experience is to lather on board the Columbus module, five plates, each containing a dozen liquid samples.
The project entitled "Foam Stability" was designed and prepared in the Department of Physics, University of Liege in the research laboratory GRASP (Group for Research & Applications in Statistical Physics). It aims to observe the behavior of bubbles in the foam which, by the agitation of liquids, occur in a state ofweightlessness. Frank De Winne, Belgian astronaut took the road to International Space Station (ISS), on the outskirts of the Soyuz TMA-15 will be responsible for monitoring the outbreak and to monitor the evolution of bubbles in foams.

This experience of foams in space, on a sixty specimens, is a first both for its originality than for its scientific educational.
HTML clipboardWhen tested during parabolic flights, the researchers found that liege liquids that do not lather in a state of gravity cause a stable foam in microgravity. The objective is to deepen this discovery to create new products with other properties. The availability of sixty tubes can test a wide range of samples, such as liquids containing nano-particles which stabilize or destabilize the foam.
Project coordination Foam Stability is ensured primarily by the team of teachers and Nicolas Vandewalle Hervé Caps exercising in the basic research laboratory of the Physics Department of the ULg and the Grapes.
