A Model for Collisional Exchange in Gas/Liquid/Solid Fluidized Beds
A new model is presented by O’Rourke, Zhao, and Snider for numerical simulations of collisional transfer of mass, momentum and energy in gas/liquid/solid fluidized beds.
Pressure and Temperature Effects in Fluid-Particle Systems
Most investigations of fluidization parameters take place at ambi- ent temperature and pressure. Yet, nearly all processes operate at elevated temperature, and many at elevated pressure.
Gas Distributor and Plenum Design in Fluidized Beds
The gas distributor (also called a grid) in a fluidized bed reactor is intended to induce a uniform and stable fluidization across the entire bed
cross-section, operate for long periods (years) without plugging or breaking, minimize weepage of solids into the plenum beneath the grid, minimize attrition of the bed material, and support the weight of the bed material during start-up and shut-down.
