Velocity profile of granular flows inside silos and hoppers
Jaehyuk Choi, Arshad Kudrolli, Martin Z. Bazant
We measure the flow of granular materials inside a quasi-two dimensional silo as it drains and compare the data with some existing models. The particles inside the silo are imaged…
Steady advection-diffusion around finite absorbers in two-dimensional potential flows
Jaehyuk Choi, Dionisios Margetis, Todd M. Squires +1
We perform an exhaustive study of the simplest, nontrivial problem in advection-diffusion -- a finite absorber of arbitrary cross section in a steady two-dimensional potential flow…
Diffusion and mixing in gravity-driven dense granular flows
Jaehyuk Choi, A. Kudrolli, R. R. Rosales +1
We study the transport properties of particles draining from a silo using imaging and direct particle tracking. The particle displacements show a universal transition from super-di…
