HE Fixed and Fluidised Bed Unit (Model: BP 23) has been designed for students’ experiments to obtain visual understanding and quantitative results on the flow of fluid through both fixed and fluidised bed of solid particles. The unit is capable of running both air and water as the flow medium. With the provision of two columns, different fluidised bed behaviour can be compared simultaneously. The unit is also capable of demonstrating basic characteristics such are bed expansion, presure drop, aggregative and particulate fluidisation, and the bubbling phenomenon. Instrumentations are provided for the complete measurements of flow rate and pressure.
