Flow in a Bubble Column Reactor

This example illustrates multiphase flow modeling in a bubble column reactor. The reactor is filled with water and gas bubbles are injected from the bottom. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid. Furthermore, as the bubbles rise through the water, gas dissolves from the bubbles into the liquid.

The example uses the macroscopic, two-phase flow model provided in the Bubbly Flow application mode, which tracks the averaged phase concentration rather than each bubble in detail.

The model accounts for dissolution of the gas into the liquid and, thus, also solves for the concentration gas dissolved in liquid.

MULTIPHASE FLOW: A reactor is filled with water while gas bubbles are sparged from the bottom, inducing a circulating motion of the liquid. Furthermore, as the bubbles rise through the water, gas dissolves from the bubbles into the liquid.
