Gas‐liquid/gas‐liquid‐solid systems are widely used in the chemical process industry for a variety of applications. In the present work, we have characterized the dynamics of gas‐liquid/gas‐liquid‐solid flows in cylindrical bubble columns using experiments and CFD simulations. The low frequency oscillations corresponding to the local re‐circulatory flow were characterized using wall pressure fluctuation measurements. Eulerian‐Eulerian two‐/three‐phase simulations were carried out with a focus on characterizing the dynamic properties of gas‐liquid/gas‐liquid‐solid flows. The effects of superficial gas velocity,H/Dratio and solid loading on the dynamic and time‐averaged flow behavior were studied experimentally and computationally. The simulated results were compared with the experimental measurements. The results presented are useful for understanding the dynamics of gas‐liquid/gas‐liquid‐solid flows in bubble columns and provide a basis for further development of CFD models for three‐phase systems.
