These images (in French) summarizes our work in patnership with the Process & Fluid Dynamics department. The objective was to model a bubble column and to validate it by comparing the results with experimental data obtained by Koide and its team from the Tokyo Chemical Engineering Institute. The work was done at the IMFT, under supervision from O. Simonin, V. Roig, H. Neau, A. Gobin. The code was Estet-Astrid ( a diphasic flows specialized code developped by EDF and Simulog) running on a Silicon Graphics station. Ensight 6 was used for post-processing.
