The influence of the bubble size, turbulence models and the grid size on the gas hold-up and the axial liquid velocity were evaluated. The results for the gas hold-up and liquid axial velocity shows good agreement with experimental data from literature. The modelling results suggest that the two-phase k-ε turbulence model is more appropriate for bubble column operating at high gas loading (of approx. 30% hold-up) and the assumption of a monodispersed bubble size is adequate for bubble column simulation. 2011-09-07T18:57:18Z 2011-09-07T18:57:18Z 2009-12 Article The Journal of the Institution of Engineers, Malaysia, vol. 70(4), 2009, pages 57-64 0126-513X http://www.myiem.org.my/content/iem_journal_2009-180.aspx http://hdl.handle.net/123456789/13676 en The Institution of Engineers, Malaysia |
