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.

A concept for a simple test bench has already been developed to establish the Thermo-PIV measurement technology at the ITS. As part of this work, the existing concept is to be reviewed and revised. The test bench will then be designed and manufactured.

The work consists of the following work packages:

• Familiarization with the topics of film cooling, PIV and thermo-PIV
• Review and revision of the already developed test bench concept
• Design and manufacture of the concept
• Initial instrumentation of the test bench
