abstract = "In simulations of fluidized beds using computational fluid
dynamics (CFD), the description of gassolid flow hydrodynamics
relies on a drag model to account for the momentum transfer
between gas and solid phases. Although several studies of drag
models have been published, there have been few investigations of
the application of lattice Boltzmann method (LBM)-based drag
models to bubbling fluidized bed simulations. In the present
study, a comprehensive comparison of empirical and LBM-based drag
models was carried out to assess the performance of these models
during simulations of gassolid flow hydrodynamics in a bubbling
fluidized bed. A CFD model using the MFIX code based on the
EulerianEulerian approach and the kinetic theory of granular flow
was used to simulate a 2D bubbling fluidized bed with Geldart B
particles. The simulation results were validated by comparison
with experimental data. Statistical analysis of the results shows
that LBM-based drag models can reliably model gassolid flow
hydrodynamics in a bubbling fluidized bed.",
