DESCRIPTION

The Fluid Science range is an innovative suite of products designed to enable students to gain an understanding of the fundamentals of Fluid Mechanics and Thermo Fluids by the process of learning via hands-on experimentation.

The high precision elements are supplied as modular tray-based systems which operate in conjunction with the Fluid Science service unit, multifunctional work panel and instrumentation enabling the student to conduct their own individual or group experiments.

The experiments are supplied with a highly visual user-friendly operational guide, allowing the students to understand the theory of the subject by the application of practical experimentation.

The FS-4.1 Fluidised Bed tray introduces students to the concepts of bed fluidisation commonly encountered both in nature and in industry. Natural occurrences include the movement of ground water, the movement of crude petroleum or the movement of natural gas through porous media. Industrial occurrences include operations such as back-washing filters, ion-exchange processes, extraction of soluble components from raw materials and certain types of chemical reactor.

The experiment contains small-diameter glass beads in a clear glass cylinder. The drop in pressure between the inlet and outlet of the cylinder is measured as the water flows through the bed. Whilst visually allowing the students to observe the particle behaviour as the flow rate increases they can monitor the difference in pressure on flow rate to the point of fluidisation and beyond.
