Cover Story: A new methodology combining Monte Carlo N-Particle (MCNP) simulation and automated radioactive particle tracking (RPT) calibration was developed to study the impact of dense internals on hydrodynamics in bubble columns. Measurements were performed in a 6-inch Plexiglas column using an air–water system at a superficial gas velocity of 40 cm/s. Vertical Plexiglas rods covered approximately 25% of the column's cross-sectional area. The findings revealed that the internals increased liquid velocity near the column center by over 30%, resulting in improved liquid circulation and increased frequency of liquid eddy movement. Additionally, the use of vertical internals led to reduced turbulence parameters, attributed to diminished velocity fluctuations. View this paper
