Effect of Bed Diameter on the Hydrodynamics of Gas-Solid Fluidized Beds

Effect of scale on the hydrodynamics of gas-solid fluidized beds was investigated in two fluidized beds of 152 mm and 78 mm in diameter.  Air at room temperature was used as the fluidizing gas in the bed of sand particles. The Radioactive Particle Tracking (RPT) technique was employed to obtain the instantaneous positions of the particles at every 20 ms of the experiments. These data were u...

Effect of Novel Swirl Distributor Plate on Hydrodynamics of Fluidized Bed Gasifier

The main advantage of a fluidized bed is its capability in excellent gas-fuel mixing. However, due to the lacks of gas radial momentum, its lateral mixing of gas-solid is not adequate. Therefore, this research is focused on fluidized bed hydrodynamics enhancement using the modified gas distributor plate design. For getting an optimum fluidized bed hydrodynamics prediction, three different class...

Fluidized Bed Processing for Multiparticulates

World wide in pharmaceutical industry, fluid bed processing technology emerged as useful application. Batch type fluid processes are using in pharmaceutical industry since 30 years. Originating in Europe, this technology gradually found its way into U.S. manufacturing facilities, beginning with the use of fluid bed dryers. The earliest fluid bed dryers were a cabinet type construction with a si...
