The laboratory work is designed to study the properties of the upward flow of fluid and gas through a column packed with glass beads of different size. The experimental rig Armfield CEL-MKII is applied. The upward flow generates fluidization, namely the state when the glass beads suspend in the flow. The pressure drops of water and air fluidization, as well as the behaviour of glass beads of different sizes are studied. The Carman-Kozeny equation was applied for calculation pressure drop in the system. The calculated values of the fluidization pressure drop correspond well with the experimental values.
The processes Continue reading...
