Application of fluidised beds is more widespread in industry than is usually appreciated, covering such diverse fields as power generation to food processing. The objective of the Fluidisation and Fluid Bed Heat Transfer Unit is to investigate the gas flow through a fixed and fluidised bed and to measure the heat transfer rate and coefficients for comparison with convective heat transfer rates in air.
Fluidisation and Fluid Bed Heat Transfer Unit takes place within a transparent chamber and the range of bed material supplied can be rapidly changed. Alternative locally sourced bed materials and air distributors can be easily utilised for student project work.
Experimental Capabilities of
Fluidisation and Fluid Bed Heat Transfer Unit:
    Observation of the behaviour in a fluidised bed of a wide range of granular materials, from onset of fluidisation to entrainment.
    Measurement of air flow and pressure drop through a variety of granular materials, as packed and as fluidised beds.
    Investigation of the effect of distributor design on bed behaviour.
    Investigation of the effect of:
    Superficial velocity
    Depth of immersion
    particle size
