Abstract

The effect of temperature on the fluidization behavior of nanoparticles agglomerates in a fluidized bed was investigated. Moreover, a model was developed based on the force balance between drag, collision, buoyancy and gravitational forces as separation forces and van der Waals force as the attractive force. Results showed that the size of agglomerates decrease by increasing the gas velocity at constant temperature. In addition, the minimum fluidization velocity and the agglomerate size increase with increasing the temperature due to increasing the van der Waals cohesive force. The agglomerate size calculated by the present model is in good agreement with the experimental data.
