When Does Slugging Occurs in Fluidization?

A single slug is observed when the pressure fluctuation spike passes through the datum established at the minimum fluidization condition while complete slugging is obtained when the slug frequency is constant for any change in the gas velocity. For larger particles (diameter above 500 µm), Dimattia et al.

What is slugging in fluidization?

The slug flow (or slugging) regime arises in gas-fluidized beds when bubbles grow sufficiently large that their shapes and rising velocities are mainly determined by the diameter of the column in which they are found.

What can be done in order to prevent slugging in the fluidized bed?

Explanation: Placing baffles will break the bubbles, increasing the diameter will reduce chances of slugging, distributor design also decides the slugging factor.
