Turbulent Multiphase Jets - a contribution to honor Prof. Graeme Jameson

Turbulent multiphase jets appear in machines used for enhanced flotation processes like the Concorde Cell and the REFLUX Flotation Cell. Likewise, flow structures generated in conventional mechanically stirred rotor-stator cells bear strong resemblance to jets. In contrast to their single-phase counterparts however, they have not been extensively studied yet. In the invited talk we present experimental and numerical methods that are available for this purpose, specifically shadowgraphy and particle image velocimetry on the experimental side and the Eulerian multi-fluid framework for multiphase CFD simulations. The corresponding numerical approach pursued at HZDR is presented. First preliminary results of both bubbly and particulate two-phase jets as well a three-phase jets are presented.
