Study air fluidization of solid particles

Characterise the solid to be fluidized.

Apply experimental fluidization equations :

Define the ΔP graph for the fluidized bed as a function of air flow rate

Determine the minimum fluidization velocity

Influence of the height of the bed of particles


Understand the operation of a cyclone
