Many industrial processes rely on cocurrent three-phase fluidization operations; however, prior experimental investigations primarily focused on low-viscosity liquids. This study aims to address the gap in knowledge by providing experimental data on phase holdup in cocurrent three-phase fluidized beds utilizing moderately viscous liquids. A series of experiments were conducted in a 76.2 mm diameter and 1.1 m high plexiglass column, employing glass beads of varying diameters and densities while using air as the gas phase and liquid phases with viscosity ranging from 10 to 120 mPa·s. Various empirical correlations were analyzed, leading to proposed modifications that account for the effects of liquid viscosity. The analysis of holdup data employed bubble wake models, highlighting their limitations in accurately predicting behaviors. Overall, the findings contribute valuable insights into the dynamics of cocurrent three-phase fluidization with viscous liquids, enhancing the understanding necessary for optimizing industrial applications.
