Clogging of cohesive particles in a two-dimensional hopper
Johnathan Hoggarth, Pablo E. Illing, Eric R. Weeks +1
We study clogging of cohesive particles in a 2D hopper with experiments and simulations. The system consists of buoyant, monodisperse oil droplets in an aqueous solution, where the…
Simple Method for the Direct Measurement of Cohesive Forces Between Microscopic Particles
Johnathan Hoggarth, Kari Dalnoki-Veress
We present a simple and inexpensive method for measuring weak cohesive interactions. This technique is applied to the specific case of oil droplets with a depletion interaction, di…
Spreading of a 2D granular analogue of a liquid puddle: predicting the structure and dynamics through a continuum model
Johnathan Hoggarth, Jean-Christophe Ono-dit-Biot, Kari Dalnoki-Veress
When sand flows out of a funnel onto a surface, a three dimensional pile that is stabilized by friction grows taller as it spreads. Here we investigate an idealized two dimensional…
