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…
The Spot Model for random-packing dynamics
Martin Z. Bazant
The diffusion and flow of amorphous materials, such as glasses and granular materials, has resisted a simple microscopic description, analogous to defect theories for crystals. Ear…
Electrochemical Thin Films At and Above the Classical Limiting Current
Kevin T. Chu, Martin Z. Bazant
We study a model electrochemical thin film at dc currents exceeding the classical diffusion-limited value. The mathematical problem involves the steady Poisson-Nernst-Planck equati…
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…
A Theory of Cooperative Diffusion in Dense Granular Flows
Martin Z. Bazant
Dilute granular flows are routinely described by collisional kinetic theory, but dense flows require a fundamentally different approach, due to long-lasting, many-body contacts. In…
Induced-Charge Electro-Osmosis
Todd M. Squires, Martin Z. Bazant
We describe the general phenomenon of `induced-charge electro-osmosis' (ICEO) -- the nonlinear electro-osmotic slip that occurs when an applied field acts on the ionic charge it {\…
