Impact cratering in sand: Comparing solid and liquid intruders
Rianne de Jong, Song-Chuan Zhao, Diana Garcia-Gonzalez +2
How does the impact of a deformable droplet on a granular bed differ from that caused by a solid impactor of similar size and density? Here, we experimentally study this question a…
Growth of a bubble cloud in CO2-saturated water in microgravity
Patricia Vega-Martínez, Javier Rodríguez-Rodríguez, Devaraj van der Meer
The diffusion-driven growth of a dense cloud of bubbles immersed in a gas-supersaturated liquid is a problem that finds applications in several modern technologies such as solvent-…
Experiments and characterization of low-frequency oscillations in a granular column
Loreto Oyarte-Gálvez, Nicolás Rivas, Devaraj van der Meer
The behaviour of a vertically vibrated granular bed is reminiscent of a liquid in that it exhibits many phenomena such as convection and Faraday-like surface waves. However, when t…
Dramatic effect of fluid chemistry on cornstarch suspensions: linking particle interactions to macroscopic rheology
Loreto Oyarte Galvez, Sissi de Beer, Devaraj van der Meer +1
Suspensions of cornstarch in water exhibit strong dynamic shear-thickening. We show that partly replacing water by ethanol strongly alters the suspension rheology. We perform stead…
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…
From the granular Leidenfrost state to buoyancy-driven convection
Nicolas Rivas, Anthony R. Thornton, Stefan Luding +1
Grains inside a vertically vibrated box undergo a transition from a density inverted and horizontally homogeneous state, referred to as the granular Leidenfrost state, to a buoyanc…
