Hydrodynamics characteristics and flow behavior of
dried TiO2 agglomerates have been studied
experimentally and computationally in a conical lab-
scale fluidized bed. The two-fluid flow model including
kinetic theory of granular flow and agglomerates based
approach was used in CFD simulations and their results
were validated by comparison with the experimental
data obtained by optical fiber probe technique.
Simulated results show that the solid volume fraction
and solid velocity along the bed height were in good
agreement with the experimental data and also
distribution of diameter of TiO2 agglomerates along the
bed height was obtained from simulation results
