| description | Computational fluid dynamic (CFD) simulation has been maturing over the last few
decades. In this thesis, CFD is employed to predict and study the hydrodynamic flow in
the impeller stirred tank. The numerical results captured the formation of re-circulation
zone near the inlet and toroidal segregated regions above and below the impellers in the
laminar mixing condition. While in the turbulent regime, multiple vortices, chaotic flow
pattern and strong radial impeller discharge were observed. Specifically, the simulated
numerical results of laminar and turbulent batch reactor were compared with
experimental data obtained from literature research. A very good agreement was found
for qualitative comparison but a less satisfactory result was found for quantitative
comparison. In addition, the effects of inlet and outlet arrangement of laminar continuous
stirred tank reactor were examined using CFD simulation and it was deduced that offcentre
positioning of inlet and outlet would give rise to asymmetric flow pattern that
would erode the toroidal segregated regions and enhance the mixing efficiency. |
