The fluidization behavior of a solid particle bed is described by the Navier-Stokes equation. Fluidization occurs when an upward flow of fluid is used to suspend and mobilize solid particles.

Sand was used for the fixed bed and air was used for fluidization. During testing, the flow of air was manually adjusted until fluidization of the sand bed was observed.
