The Chair of Thermal Turbomachinery and Aero Engines is working on several projects, which are mainly financed by public funding programs (DFG, BMWi, MERCUR), but also in cooperation with different industrial partners.
In the following, you will find an overview of the projects currently being worked on at the chair as well as those already completed.
In the DFG joint project PAK 948, the influence of blade wakes on the near-wall unsteady flow in axial turbine ring grids is investigated using a combination of time-resolved measurement methods (hot-wire measurements, surface hot-film arrays) and scale-resolved numerical simulation methods (Large Eddy Simulations (LES)).
The transient development of secondary flow structures under periodic wake influence is investigated within the DFG joint project (PAK948). For this purpose, the flow in the institute's own large-scale model turbine is measured using high-resolution measurement technology (hot-wire anemometry).
The operating point-dependent, highly unsteady flow fields that arise within steam extraction modules are being investigated as part of the project "Experimental analysis of the flow in a generic extraction module" funded by the Mercator Research Center Ruhr.
In cooperation with MAN Energy Solutions, interaction mechanisms in multi-stage high-/medium-pressure steam turbine modules are investigated experimentally and numerically in the research project "SchauTex". The 4-stage air turbine with a pressure ratio of 2.7 and a power of approx. 1.5MW is used as a test rig.
