What we do
The Axial Turbines Group focuses on aerodynamic problems regarding multi-stage axial turbines such as jet engines and turbines for power generation in combined cycle power plants as well as the aero-elasticity of wind turbines. As part of the Collaborative Research Center (SFB) 871, the group addresses innovative methods of health monitoring of aircraft engines. A wide variety of test facilities (e.g. axial air turbine, diffuser rig and rotor blade deformation test rig) and software packages are available for research.
Multi-Stage Axial Turbines
The volatile power supply generated from renewable energy sources such as wind and solar power demands improved flexibility (i.e. short start-up and shut-down intervals) and increasing part-load operation time spans from conventional and combined-cycle power stations. Simultaneously, it is essential to optimise output efficiencies for a wide spectrum of operating points. The Turbine Group conducts numerical simulations and experimental investigations of multi-stage turbines aiming to gain a more detailed comprehension of steady and unsteady state flow phenomena in turbines and diffusers and to use new insights for the improvement of their respective efficiencies. In particular the interdependencies of influencing factors of both components are investigated. In addition to the analysis of local effects in the flow path, the effectiveness of measures aimed at the reduction of local loss generation in multi-stage turbomachinery is studied using high-pressure steam turbine blades as a test case.
