CFD simulation of gas-liquid flow in tray columns (Id 304)

Owing to increased energy supply from renewable sources a more flexible operation of such apparatuses is already demanded. However, enlarged over- and underload modes are challenging with respect to design. Basically, computational fluid dynamics provide a powerful support by predicting the complex two-phase flow on the tray. Nevertheless, further developments are particularly needed for valve trays in order to reliably simulate macroscopic flow scenarios.
Within the frame of a current research project we offer a student internship position for further development of a multi-phase CFD set-up that maps the individual gas inlets by point-like mass and momentum sources. Special focus is put on the influence of different valve geometries and experimental data is available from parallel student projects.
