摘要：

Numerical investigation of flow hydrodynamics in a square cross-sectioned bubble column was conducted in a transient Euler-Euler environment by applying the simulation tool Ansys CFX 14.0. The influence of the drag coefficient (CD) was investigated and the results were also compared with drag force models. Furthermore, three different lift force models and a defined lift coefficient were studied. All results were compared with the available experimental data. All simulations were carried out for a single-hole sparger with given aspect ratio (H/D) and superficial gas velocity.
