Dimensionless Number Group Analysis of Surface-Treated Powders
Powders, 2023 Modeling powder properties remains a complex and difficult area of study because particulate materials can behave differently under variable conditions based on their bulk and surface-level properties.

Minimum and Full Fluidization Velocity for Alumina Used in the Aluminum Smelter
International Journal of Engineering Business Management, 2011 Fluidization is an engineering unit operation that occurs when a fluid (liquid or gas) ascends through a bed of particles, and these particles get a velocity of minimum fluidization V mf enough to stay in suspension, but without carrying them in the ...

A Study of Fluctuation and Expansion Ratios for Gas-Solid Fluidized Columns
Journal of Engineering, 2020 The fluctuation and expansion ratios have been studied for cylindrical gas-solid fluidized columns by using air as fluidizing medium and Paracetamol as the bed material. The variables were the column diameter (0.0762, 0.15, and 0.18 m), static bed height

Evaluation of correlations for minimum fluidization velocity (U) in gas-solid fluidization
Powder Technology, 2018 Abstract The minimum fluidization velocity (Umf), defined as the superficial gas velocity at which the drag force of the upward moving gas becomes equal to the weight of the particles in the bed, is one of the most important parameters associated with a fluidized bed system.

Minimum Fluidization Velocity and Reduction Behavior of Combusted Iron Powder in a Fluidized Bed
SSRN Electronic Journal, 2022 The fluidization and reduction behavior of micron-sized iron oxide powder, produced by iron combustion, is studied in a lab-scale cylindrical fluidized bed. The minimum fluidization velocity umf is found to stabilize above normalized static bed heights of 0.5 H/D (static bed height divided by the bed diameter).
