On Turbulent Swirling Jets: Vortex Breakdown, Coherent Structures, and their Control
… kohärenter Strukturen in turbulenten Drallstrahlen. Die untersuchte Strö-mungskonfiguration zeichnet sich durch eine hohe Komplexität aufgrund gleichzeitig auftretender axialer und azimutaler Scherschichten aus. Darüber hinaus tritt ab einer gewissen Drallintensität ein Phänomen auf, …

Investigation of cluster nozzle concepts for direct injection diesel engines
For last several decades, there has been a lot of research about DI (Direct Injection) diesel engines because they have a clear advantage in terms of CO2 (Carbon Dioxide) emissions compared to gasoline engines. Furthermore, because of its ability to operate at low equivalence ratios, the diesel …

Two-phase CFD analyses in fuel assembly sub-channels of Pressurized Water Reactors under swirl conditions
Single-phase CFD calculations are already widely applied in nuclear industry for the thermal-hydraulic design optimization of fuel assemblies (FA). In contrast, two-phase CFD-applications are still in the state of development. The work presented in this thesis shows contributions towards the …
