ABSTRACT

Two-phase (solid and gas) 2D fluidized bed reactor’s flow pattern was investigated. Computational fluid dynamics (CFD) simulation results were compared with those obtained experimentally. The CFD simulation is carried out using commercial software “Fluent”. Experiment is carried out in a fluidized bed containing spherical glass beads of diameter 300–350 μm. Initial volume fraction is fixed as 0.6. A multi-fluid Eulerian model incorporating the kinetic theory for solid particles was applied in order to simulate the gas–solid flow. Momentum exchange coefficients are calculated using Syamlal–O’Brien drag function. The kinetic energy lost during inter-particle collisions were characterized by specifying the restitution coefficient values from 0.9 to 0.99. The pressure drop and bed expansion ratio for various superficial velocities are compared with experimental results. More... »
