A STUDY OF PRESSURE-DROP FLUCTUATIONS IN A GAS-SOLIDS FLUIDIZED-BED

A model is proposed which relates the amplitude of the pressure drop f luctuations across a gas-solids fluidized bed to geometry and physical properties of the bed and the particles. The model is based on the en ergy balance around the fluidized bed. The proposed model predictions for amplitude of pressure drop fluctuations agree well with the experi mental data. A model for fundamental frequency of pressure fluctuation s, which was originally proposed by Baskakov, is verified using experi mental data from several sources.
