Giant drag reduction due to interstitial air in sand
Tess Homan, Devaraj van der Meer
When an object impacts onto a bed of very loose, fine sand, the drag it experiences depends on the ambient pressure in a surprising way: Drag is found to increase significantly wit…
Liquid-grain mixing suppresses droplet spreading and splashing during impact
Song-Chuan Zhao, Rianne de Jong, Devaraj van der Meer
Would a raindrop impacting on a coarse beach behave differently from that impacting on a desert of fine sand? We study this question by a series of model experiments, where the pac…
Quantfying rich patterns in agglomeration of floating beads
Ceyda Sanlı, Detlef Lohse, Devaraj van der Meer
Macroscopic spherical particles spontaneously form rich patterns on a standing Faraday wave. These patterns are found to follow a very systematic trend depending on the floater con…
Fluctuation theorems for an asymmetric rotor in a granular gas
Sylvain Joubaud, Detlef Lohse, Devaraj Van Der Meer
We investigate the validity of fluctuation theorems for an asymmetric rotor experiment in a granular gas. A first state, with a Gaussian distribution of the angular velocity, is fo…
