Pumping of liquids with traveling-wave electroosmosis
(AIP Publishing, 2005)
Net flow of electrolyte induced by a traveling-wave electric potential applied to an array of microelectrodes is reported. Two fluid flow regimes have been observed: at small-voltage amplitudes the fluid flow follows the ...

Self-Diffusion in a Gas-Fluidized Bed of Fine Powder
(American Physical Society, 2001)
We have investigated the self-diffusion in a stable gas-fluidized bed of fine powder. Two regimes have been observed: for gas velocities yg above the minimum fluidization velocity ym and below a critical gas velocity yc ...

High viscosity gas fluidization of fine particles: An extended window of quasihomogeneous flow
(American Physical Society, 2006)
We explore the role of gas viscosity in the behavior of gas-fluidized beds of fine powders by means of experimental measurements using nitrogen and neon as fluidizing gases, and theoretical considerations. The existence ...
