Task

The cooling of thermally highly stressed components plays a key role in modern gas turbines and aircraft engines. At ITS, the cooling air-hot gas interaction during film cooling blow-out is being investigated experimentally using stereoscopic particle image velocimetry (SPIV) in order to measure time-resolved velocity fields. In future, these measurements are to be supplemented by temperature field measurements using laser-induced phosphorescence (LIP) to create what is known as Thermo-PIV.

In order to test the suitability of Thermo-PIV for the existing setup and to gain initial experience with the measurement method, a test bench including components is to be designed as part of this work. The final concept is to be produced at the end of the work and used for initial trial measurements.

The work consists of the following work packages:

• Familiarization with the topics of film cooling, PIV and thermal PIV
• Selection of a suitable reference test case
• Selection of the components required for LIP measurements
• Conceptual design and construction of a test bench based on the selected test case
