Granular Media under Vibration in Zero Gravity: Transition from Rattling to Granular Gas

TL;DR

This study investigates how granular materials behave under vibration in zero gravity, focusing on the transition from rattling to granular gas states, using experimental data collected during parabolic flights.

Contribution

It provides experimental insights into the behavior of granular media in zero gravity, highlighting the transition mechanisms from rattling to granular gas states.

Findings

Quantified the effect of g-jitter on granular behavior.

Documented the transition from rattling to granular gas.

Used high-speed imaging to analyze particle dynamics.

Abstract

We report on different experimental behaviours of granular dissipative matter excited by vibration as studied during the 43rd ESA campaign of Airbus A300-0g from CNES. The effect of g-jitter is quantified through the generation of a rattle effect. The French-European team's electromagnetic set-up is used, with 20Hz cam recording and high speed camera for a short duration (1s) during each parabola.
