A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles. The resulting medium then has … See more A fluidized bed consists of fluid-solid mixture that exhibits fluid-like properties. As such, the upper surface of the bed is relatively horizontal, which is analogous to hydrostatic behavior. The bed can be considered to be a … See more In 1922, Fritz Winkler made the first industrial application of fluidization in a reactor for a coal gasification process. In 1942, the first … See more Basic model When the packed bed has a fluid passed over it, the pressure drop of the fluid is approximately proportional to the fluid's superficial velocity. … See more • Video: Liquid-Solid Fluidized Bed • US DOE Fluidized Bed Technology – Overview website • US DOE NETL Fact Sheet See more Fluidized beds are used as a technical process which has the ability to promote high levels of contact between gases and solids.
