Description

Video clips show hydrodynamic behaviors in the fluidized bed column using perforated plate distributors and slotted distributors with inclination angles of 30, 45 and 60 degrees. The vertical velocity component results in vertical motions of particles. Swirling motions of particles are caused by the horizontal velocity component. For slotted distributors, swirling motions of particles are observed above the distributors. As the inclination angle increases, the bed expansion increases due to a higher value of the vertical velocity component. In the case of perforated plate distributors, the largest bed expansion is obtained.

Steps to reproduce

The fluidized bed column is made of acrylic with inner diameter 0.14 m and height 1 m. The head of the column is made of stainless steel (SS304). The cyclone is connected to the head of the column to collect some particles from the outlet stream. The gas monomer is supplied using a blower (Ventex model 2RB). The bed pressure is measured using a pressure transducer (Nagano model ADZ - SML - 10). Biopolyethylene particles are used as the bed material. Flow behaviors are recorded using a high-speed video camera.
