Quantitative coarse graining of laminar fluid flow penetration in rough boundaries
Akankshya Majhi, Lars Kool, Jasper van der Gucht +1
The interaction between a fluid and a wall is described with a certain boundary condition for the fluid velocity at the wall. To understand how fluids behave near a rough wall, the…
Darcy-Reynolds forces during intrusion into granular-fluid beds
Joshua Strader, Neil Causley, Joshua A. Dijksman +1
We experimentally study intrusion into fluid-saturated granular beds by a free-falling sphere, varying particle size and fluid viscosity. We test our results against Darcy-Reynolds…
Viscous-like forces control the impact response of shear-thickening dense suspensions
Marc-Andre Brassard, Neil Causley, Nasser Krizou +2
We experimentally and theoretically study impacts into dense cornstarch and water suspensions. We vary impact speed as well as intruder size, shape, and mass, and we characterize t…
Sheared Amorphous Packings Display Two Separate Particle Transport Mechanisms
Dong Wang, Joshua A. Dijksman, Jonathan Bares +2
Shearing granular materials induces non-affine displacements. Such non-affine displacements have been studied extensively, and are known to correlate with plasticity and other mech…
Enlightening force chains: a review of photoelasticimetry in granular matter
Aghil Abed Zadeh, Jonathan Barés, Theodore A. Brzinski +10
A photoelastic material will reveal its internal stresses when observed through polarizing filters. This eye-catching property has enlightened our understanding of granular materia…
Thermal Marangoni-driven Dynamics of Spinning Liquid Films
Joshua A. Dijksman, Shomeek Mukhopadhyay, Robert P. Behringer +1
Spin coating of thin films of viscous liquids on a rotating substrate is a core technological component of semiconductor microchip fabrication. The thinning dynamics is influenced…
