摘要：

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