Infrastructure
Low Speed Research Compressor (LSRC)
- scaled, low-speed 1- to 4-stage compressor model
- Validation of novel versions of blading
- Investigation of flow structures at the stability limit of compressors
- Influencing the secondary flows in compressor cascades
- Active and passive flow control to extend the stable operating range
- continuously operating, open wind tunnel
- operating from the low speed range up to high subsonic inflow by optional drive using blowers or compressors
- investigation of turbine or compressor bladings
- simulation of the rotor-stator interaction
by moving bar wake generators
Transonic Turbines Cascade Wind Tunnel (TTGWK)
- Investigation of transonic turbine cascades at very low aspect ratios
- Inflow Mach number ~0.25 / Outflow Mach number up to ~1.2
- Access for optical measurement methods (for example, background Schlieren optics)
Plate film cooling channel (PFKK)
- Rectangular channel for the investigation of film cooling, and internal heat transfer in the cooled turbine blades
- Plexiglas channel with good optical access for laser optical flow measurements and heat transfer measurements by TLC method
- continuously operating open wind tunnel in suction mode (Eiffel channel)
- low Mach number low turbulence of the inflow

- 6 axis robot
- Max. rotational diameter of 80cm
Control valve for steam turbines
- Scaled control valve for the experimental investigation of the valve's unsteady operating behaviour
- Optical flow pattern should reveal interactions and exisiting mechanics
- Developed as part of the COORETEC project "Grüne Erde" in 2017
- Gas turbine as package with all parts for experimental investigation of the flow inside of an acoustic hood
- Simulation of different setups for example the normal operation, failure of fan groups or modified conditions for the inflow
- Gas turbine and auxiliary power unit with high accuracy and a scale of 1:3
