Space GrainsThe aim of the Space Grains project is to study the dynamics and the statistical mechanics of an ensemble of particles that dissipates due to collisions. The experiments focus on clustering mechanisms, thermal fluctuations, convection, segregation and physical phenomena related to excited granular systems.
Coordination : E.Falcon and N.Vandewalle.

Following the joint proposal GRANULOGY between Europe (ESA) and China (CMSA), a meeting took place at Liège (26 June 2018) with Chinese and European members of Space Grains. A clear common interest is to optimize the use of ISS … Continue reading
The Space Grains collaboration used the Vip-Gran instrument during the 69th ESA Parabolic Flight Campaign, 16 – 26 April, 2018 at Novespace, Bordeaux (France). Dynamics of Brownian-like particles moving in a thermalized granular gas has been investigated.
The workshop will be held in MSC laboratory, Université Paris Diderot, Paris, France, on 12-13 March 2018 to prepare the 6th Parabolic Flight Campaign (ESA PFC69) of the Vip-Gran instrument. ESA PFC69 campaign is scheduled from 16 to 27 April … Continue reading
The Space Grains collaboration will use the Vip-Gran instrument during the 67th ESA Parabolic Flight Campaign, November 6 to November 16, 2017 at Novespace, Bordeaux (France)
The fourth parabolic flight campaign (PFC66) of the Vip-Gran instrument were performed in Bordeaux (France) in May 2017. We observe for the first time a transition for rods between a gas-like regime of to a cluster-like regime when the density … Continue reading
The Space Grains collaboration will use the Vip-Gran instrument during the 66th ESA Parabolic Flight Campaign, May 9 to May 19, 2017 at Novespace, Bordeaux (France)
The meeting is dedicated to prepare the 4th Parabolic Flight Campaign (ESA PFC66) of the Vip-Gran instrument. We will define the sets of parameters for the 3 flights of the PFC66 campaign scheduled from 9 to 20 May 2017. The … Continue reading
The goal was to defined the ESR (Experimental Scientific Requirements) for the ISS prototype of the Vip-Gran instrument. Various cells have been defined, among them: 3D and 2D dry cells, Wet cell, Sound cell, Shear cell…
