A Numerical Study on Agglomeration in High Temperature Fluidized beds
Soft-sphere discrete element method (DEM) and Navier-Stokes equations were coupled with equations of energy for gas and solids to investigate the process of agglomeration in fluidized bed of polyethylene particles at high temperature. The Newton’s second law of motion was adapted for translational and rotational motion of particles and agglomerates. The cohesive force for polyethylene particles...
متن کاملFlow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...
متن کاملFlow Structure Formation in High-velocity Gas-fluidized Beds
-The occurrence of heterogeneous flow structures in gas-particle flows seriously affects the gas–solid contacting and transport processes in high-velocity fluidized beds. A computational study, using a discrete particle method based on Molecular Dynamics techniques, has been carried out to explore the mechanisms underlying the cluster and the core/annulus structure formation. Based on energy bu...

متن کاملGranular Pressure Measurement in Fluidized Beds
Experiments were carried out to measure the additional pressure, called the granular pressure, which is exerted on the containing wail of a fluidized bed due to particle collisions with that wall. Measurements were made for water fluidized beds using glass beads of 1.3 mm and 3 mm diameter, lead shot of 2.1 mm diameter and plastic particles. The granular pressure was observed to increase to a m...
