ABSTRACT

To simulate the dynamic characteristics of the oscillating bubble plume in a rectangular bubble column, three-dimensional transient simulations are performed using the FLUENT commercial software based on the volume of fluid (VOF) approach. In order to take into account the influence of the movement of the free surface of the liquid phase on the oscillations of the bubble plume, the numerical simulation domain corresponds to the geometrical dimensions of the column. The reproduction of the dynamic flow behavior with the VOF model dominated by the oscillating movement of the bubble plume is encouraging. The time-averaged liquid velocity field obtained from the VOF simulation shows that the liquid is entrained upflow in the core region and downflow near the walls. The simulated vertical velocity profiles are in agreement with particle image velocimetry (PIV) measurements near the column walls and at its center. The gas holdup is greater at mid height of the column; however, near the interface the gas holdup was notably reduced.
