Abstract

The discontinuous nature of liquid flow in a random packed bed is observed in many chemical engineering and metallurgical applications like blast furnace. So, to model the liquid flow in these systems, the discrete nature of the liquid flow should be taken into consideration. Moreover, the effect of gas flow on the particles and liquid phase of the packed bed, taking into account the random nature of the bed and the discrete nature of the liquid, is lacking. In this work, we study the flow behaviour of the liquid phase, taking into account the movement of particles due to the lateral gas flow. A Discrete Liquid Flow model is applied for this purpose. A graph-based Depth First Search approach is used to determine the void locations. The study is conducted for different gas flow rates and particle sizes. The study shows that the cavity/raceway size increases due to the liquid injection. The deviation of the liquid path due to the gas drag is also captured. It is found that the deviation of the liquid path is higher for the larger particle sizes. © 2023, The Indian Institute of Metals - IIM.
