## Abstract Gas‐liquid bubbly flow in 2‐D bubble columns was studied by numerical simulation. A Eulerian‐Eulerian two‐fluid model used describes the time‐dependent motion of liquid driven by small, spherical gas bubbles injected at the bottom of the columns. Such equations, numerically implemented
Gas holdup in bubble columns has been investigated over a wide range of operational and geometrical parameters. A criterion has been developed for the prediction of the transitional velocity from the homogeneous to heterogeneous flow regime. Correlations for gas holdup in both regimes are developed
