Abstract
In case of large CFBs, steady state CFD simulation can be
an attractive alternative for the time-consuming
transient simulations. In the paper, the features of
equation closure of a steady state model are evaluated on
basis of a transient 3D simulation. The computational
results are analysed to determine the averaged flow
properties and the main fluctuating components and their
correlations. The main terms to be modelled for the
steady state approach are, according to this analysis,
the average gas-particle drag force and the Reynolds
stresses arising from velocity fluctuations. Suggestions
for approaches for steady state equation closure in case
of industrial CFB applications are discussed.
