Impact on granular beds

D Van Der Meer - Annual review of fluid mechanics, 2017 - annualreviews.org
The impact of an object on a granular solid is an ubiquitous phenomenon in nature, the
scale of which ranges from the impact of a raindrop onto sand all the way to that of a large …

Dynamic characteristics of sphere impact into wet granular materials considering suction

X Zhang, D Zhang, Y Wang, S Ji, H Zhao - Granular Matter, 2023 - Springer
Understanding the impact and penetration characteristics of non-homogeneous granular
material systems is of great significance for various research work. In this study, a series of …

Experimental velocity fields and forces for a cylinder penetrating into a granular medium

A Seguin, Y Bertho, F Martinez, J Crassous… - Physical Review E …, 2013 - APS
We present here a detailed granular flow characterization together with force measurements
for the quasi-bidimensional situation of a horizontal cylinder penetrating vertically at a …

Food powder flow in extrusion: Role of particle size and composition

C McGuire, K Siliveru, K Ambrose, S Alavi - Processes, 2022 - mdpi.com
Innovations in food extrusion technology are enabling its rapid expansion and applicability
in diverse areas related to bioprocessing and value addition. This study relates raw material …

Unifying impacts in granular matter from quicksand to cornstarch

JJS Jerome, N Vandenberghe, Y Forterre - Physical Review Letters, 2016 - APS
A sharp transition between liquefaction and transient solidification is observed during impact
on a granular suspension depending on the initial packing fraction. We demonstrate, via …

Experimental investigation into the impact of a liquid droplet onto a granular bed using three-dimensional, time-resolved, particle tracking

EJ Long, GK Hargrave, JR Cooper, BGB Kitchener… - Physical Review E, 2014 - APS
An experimental investigation into the interaction that occurs between an impacting water
droplet and a granular bed of loose graded sand has been carried out. High-speed imaging …

Sphere impact and penetration into wet sand

JO Marston, IU Vakarelski, ST Thoroddsen - Physical Review E—Statistical …, 2012 - APS
We present experimental results for the penetration of a solid sphere when released onto
wet sand. We show, by measuring the final penetration depth, that the cohesion induced by …

Ray systems in granular cratering

T Sabuwala, C Butcher, G Gioia, P Chakraborty - Physical Review Letters, 2018 - APS
In classical experiments of granular cratering, a ball dropped on an evened-out bed of
grains ends up within a crater surrounded by a uniform blanket of ejecta. In this Letter, we …

Crater formation during raindrop impact on sand

R de Jong, SC Zhao, D van der Meer - Physical Review E, 2017 - APS
After a raindrop impacts on a granular bed, a crater is formed as both drop and target
deform. After an initial, transient, phase in which the maximum crater depth is reached, the …

Ray systems and craters generated by the impact of nonspherical projectiles

F Pacheco-Vázquez - Physical review letters, 2019 - APS
The impact of a spherical projectile on an evened-out granular bed generates a uniform
ejecta of material and a crater with a raised circular rim. Recently, Sabuwala et al.[Phys …
