New cooperation project: high-speed 4d measurement of thermoacoustic oscillations

NEW COOPERATION PROJECT: HIGH-SPEED 4D MEASUTRMENT OF THERMOACOUSTIC OSCILLATIONS

During the combustion of sustainable fuels, such as green hydrogen for stationary gas turbines, instabilities occur in the form of thermoacoustic oscillations. To ensure safe and efficient turbine operation, a deeper understanding of these oscillations is necessary.
For this purpose, scientists from the Chair of Measurement and Sensor Systems Engineering at TU Dresden and the Institute of Thermal Turbomachinery and Machine Dynamics at TU Graz want to develop and apply new measurement and evaluation techniques. Using modern high-speed camera technology and deep learning based tomographic reconstruction.
The aim of the project is to perform laser-optical measurements inside such oscillating flames, with high demands on the measurement technology due to the necessary spatial (3D, ≤ 500 µm³) and temporal (≤ 10 µs) resolutions.
The cooperation project is funded by the Deutsche Forschungsgemeinschaft (DFG) as well as the Austrian Science Fund (FWF) under the project numbers CZ 55/50-1 and I 5392-N. The project will start on 01.11.2022.
