Lokální charakterizace tokového pole v bublané koloně generované pomocí CFD
Fialová, Marie ; Staykov, P. ; Vlaev, S.D.
This study is aimed at 3-D simulation of bubble column using commercial CFD code Fluent and generating experimental local gas hold-up distribution profiles at different bed height positions, comparing these profiles with model solutions and demonstrating the flow field variation (vector plots for air and liquid movement) obtained by CFD modeling. Overall gas volume fraction values predicted by the CFD simulation were matched to measured values and showed comparable. CFD modeling was found to describe satisfactorily bubble bed formation in the bubble column operating with water and low viscosity solution.
