In this study, investigate and quantify, the impacts of the dense vertical internals and their sizes on the liquid velocity field, Reynolds stress and turbulent kinetic energy profiles in a bubble column with and without dense internals. These flow dynamics parameters were measurement via sophisticated radioactive particle tracking (RPT) technique. This investigation used a Plexiglas bubble column scale with outside 6-inch (14 cm) diameters at various superficial gas velocity 20 and 45 cm/s. In the bubble column, the vertical dense tubes covered area ~25% of the total crosssectional area of the column diameter which utilized in Fischer-Tropsch synthesis in different sizes 0.5 in (1.27 cm) and 1 in (2.54 cm). These vertical tubes was made from a Plexiglas material and their results were compared with empty bubble column. The presented RPT data in terms of liquid velocity field and turbulence parameter profiles would be helpful to develop, computational fluid dynamics (CFD) validation towards well prediction for flow dynamic parameters that are involved in multiphase flow bubble columns.
