Bubble columns and sparged gas-liquid systems have wide application in chemical industry and in biotechnology, being slurry bubble column (SBC) is a special case of three-phase gas-liquid-solid. In most applications, SBC are operated under pure heterogeneous hydrodynamic regime (non-uniform, churn turbulent). However, operation of slurry bubble columns (SBC) in homogeneous regime (uniform, laminar) may be preferred in some cases like in the intensification of catalytic reactors using special distributors [1] or to secure low level of shear stresses in some bioapplications [2]. Most of the research on SBC is however dedicated to pure heterogeneous regime (PHeR) and very little attention has been paid to HoR. In the present contribution we will present a systematic study of the hydrodynamic behavior of SBC equipped with fine sparger, able to give homogeneous and heterogeneous regime and transition between them.
