the flow behaviour and circulation pattern of three phase system inside
an isothermal slurry bubble column using a finite volume technique. The
three phase system consists of; air as the gas phase, non-Newtonian solution
of poly acryl amid (PAA) as the liquid phase, and alumina catalyst as
the solid phase. To experimentally validate the code, local gas hold-up
and bubble characteristics have been measured using a modified electrocondactivity
probe. The model was based on the principle of continuity and momentum
equations. The gas and liquid velocity were prescribed numerically and
the gas velocity simulated agrees with experimental observation. The experimental
results as well as the numerical results show that the gas velocity decreases
with increasing the non-Newtonian behaviour of the system and this may
due to the increasing in bubble coalescence.]]>Burgress, J.M. and P.H. Calderbank,1975Carreau, P.J., D.C.R. De Kee and R.P. Chhabra,1997Chen, Z., C. Zheng and Y. Feng,1995Clark, N.N. and R.L.
