Eulerian: Hibiki’s Bubble Column

This tutorial demonstrates how to model a Eulerian multiphase turbulent flow in Simcenter STAR-CCM+.

This simulation models Hibiki’s bubble flow column [969], which involves air and water phases being pumped through a vertical column. The geometry is shown in the diagram below.



The first part of the tutorial covers how to select the Eulerian multiphase and multiphase turbulence models, specify the properties of each phase and define the phase interaction.

In the second part of the tutorial, the S-Gamma model is activated to account for the size distribution of bubbles in the dispersed phase (air). The S-Gamma model predicts the Sauter mean diameter, which in turn is used to set the phase interaction length scale.

A validation section is also included where the results of the two simulations are compared with experimental data.
