Numerical Simulations of Hydrodynamic Behaviour in Spouted Beds

A hydrodynamic model of dense gas-solid flow was developed to predict the flow behaviour in spouted beds. Constitutive equations describing the particulate solids pressure, viscosity and elasticity moduli were implemented into a hydrodynamic simulation computer program. The resulting hydrodynamic simulations agree well with experimental measurements of time-averaged particle-and-gas velocity profiles, as well as with experimental solids concentration distributions obtained from three different articles issued from the fluidization literature.
