Abstract
Slurry bubble columns, used in environmentally-conscious industries, operate as complex three-phase systems with fluid, gas, and particles. Understanding the interactions between these phases is crucial for sustainable column design. Bubble-object interactions are investigated using a simplified two-dimensional consideration as a cylinder instead of the three-dimensional nature of particles in the fluid domain as a fixed obstacle. It is found that increasing the Weber number reduces the film thickness between the bubble and object, with bubble breakup occurring at a critical Weber number of 0.47. This approach provides insight into particle-bubble dynamics, aiding in column design optimization.
