Fluidized Bed Heat Transfer Apparatus Model TH 055
Fluidized Bed Heat Transfer Apparatus Model TH 055
Sci-tech Fluidized Bed Heat Transfer Apparatus Model TH 055 is designed to provide visual and quantitative results related to the flow of air through both a packed and a fluidized bed of granular material.
Item Description
The Unit also provides quantitative results related to heat transfer in a fluidized bed.
The Fluidization and Fluid Bed Heat Transfer Unit is almost silent in operation, is safe and easy to use and responds quickly to changes in operating conditions.
The interesting and stimulating range of investigations which are possible with this apparatus make it of interest to those involved with mechanics of fluids, Heat Transfer and Thermodynamics in courses for ‘Chemical Engineers’, ‘Energy Managers’, ‘Plant & Process Engineers’, ‘Mechanical Engineers’, and ‘Mining Engineers’.
Application of fluidized beds is more widespread in industry than is usually appreciated, covering such diverse fields as power generation to food processing. The objective of the unit is to investigate the gas flow through a fixed and fluidized bed and to measure the heat transfer rate and coefficients for comparison with convective heat transfer rates in air.
