Design and Understanding of Fluidized-Bed Reactors

The industrial deployment of the fluidized bed
reactors (FBR) have recently increased because of
their excellent heat and mass transfer
characteristics and product efficiency. In the state-
of-the art design of these reactors, computational
fluid dynamics (CFD) is a recently developed tool
which can assist in their scale up. This book
describes practical applications of multiphase CFD
models with the kinetic theory of granular flows in
bubbling, turbulent, and fluidized-bed reactors,
including both experimental and computational
approaches. It explains bubble behaviors,
hydrodynamics, and reaction kinetics that are needed
for scaling up such reactors using two multiphase
CFD codes, the IIT code and the MFIX code developed
at the NETL. It discusses two kinds of granular
temperatures to determine solid diffusions and
mixing in particle and bubble levels, and a
technique to optimize catalyst size in fluidized
catalytic reactors. This book is useful to research
engineers working on the fluidization technology, or
any researcher studying multiphase flows,
computational fluid dynamics, and fluidization.
