The unit is capable of running both air and water as the flow medium. With the provision of two columns, different fluidized bed behavior is compared simultaneously.
The unit is also be capable of demonstrating basic characteristics such as bed expansion, pressure drop, aggregative and particulate fluidization, and the bubbling phenomenon.
Instrumentations is provided for the complete measurements of flow rate and pressure.
Two acrylic cylindrical columns mounted on the back panel is filled with a bed of a chosen solid particles.
At the lower end, the cylinders have a bed support for the fixed bed, or to hold the solid particles when it is defluidised.
Wall tappings is provided on the columns to facilitate pressure drop measurements.
Separate manometers are installed to allow the pressure drop in both columns to be measured simultaneously.
The unit is equipped with sump tank with suitable pump, control valve, variable area flow meter, air pump and air discharge outlet.
The unit is designed such that the bed material can be easily changed.
Arrangements for feeding different types of solid particles needs is supplied so that a wide range of experiments is carried out on a fixed or fluidized bed.
