Fluidised beds and pneumatic transport
A fluidised bed involves two phases: a solid and a fluid (gas or liquid).
Pneumatic conveyor systems transport powderous and granular bulk solids by means of a gas flow (mostly air) in pipelines.
Fluidised bed formation
Investigation of fluidised bed formation of solids in air and water.
Comparison of fluidised beds
Two transparent columns with different diameters for observation of fluidised bed formation in gases.
