Self-Diffusion in a Gas-Fluidized Bed of Fine Powder

Valverde Millán, José Manuel; Castellanos Mata, Antonio; Sánchez Quintanilla, Miguel Angel (American Physical Society, 2001-01-01)
We have investigated the self-diffusion in a stable gas-fluidized bed of fine powder. Two regimes have been observed: for ...
