Abstract
Steady state CFD simulation would present an attractive
alternative for the computationally demanding transient
simulations in the case of large, industrial scale BFBs.
In the present paper, the features and relative
importance of the various terms appearing in steady state
flow equations are analyzed based on a transient
simulation. According to this analysis, the most
important terms in the momentum equations are the
gas-solid drag term and the solid volume fraction and gas
pressure fluctuation correlation terms. The solid
pressure and the Reynolds stress terms are also found to
be important.
