From a Hierarchy of Stochastic Differential Equations to a Hierarchy of Generalized Beta Distributions
Siqi Shao, R. A. Serota
We introduce a mean-reverting stochastic differential equation with a three-component stochastic term and show that it generates a hierarchy of steady-state (stationary) distributi…
Controlled drop generation via ligament extraction from a static or vibrating liquid bath
Johnathan Hoggarth, Daniel M. Harris, John W. M. Bush +1
We introduce a simple method for generating droplets at the surface of a liquid bath by rapidly stretching a liquid ligament with a spring-loaded cylindrical probe. By varying the…
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…
