How to handle granulates in space ?

The peculiar behavior of granular materials in microgravity is a hard physics problem. In the dilute case, granular gases loose kinetic energy and may form clusters. In order to avoid this “cooling effect”, mechanical energy should be continuously injected in … Continue reading

Maxwell’s demon in space

In our last article published in Phys. Rev. E, we show how dynamical clustering triggers the Maxwell’s demon in microgravity experiments. In the framework of the ESA SpaceGrains project, we realized numerical simulations in order to test the granular Maxwell’s … Continue reading

Pulses in a vertical granular column

We investigated the dynamics of a vertical column of 12 beads submitted to a series of taps. Impulses are strong enough to eject beads. The motion of the beads are recorded using a high-speed camera. Depending on the frequency of taps, … Continue reading
