Job Description
The “Flightpath 2050” report documents Europe’s vision for aviation to reduce pollutant emissions of NOx drastically. Rich-Quench-Lean combustors (RQL) are chamber designs with lower NOx emissions and are currently in operation with kerosene. The fuel change from kerosene to hydrogen in RQL combustion chambers is considered a step closer to decarbonization. With this change, combustion instabilities, such as the Growl/Rumble phenomenon, might occur. This phenomenon describes a low-frequency noise that can damage the engines. Entropy and equivalence ratio waves are suspected as possible causes for this phenomenon.
This student thesis is the first step toward the investigation of Growl/Rumble in an RQL combustion chamber. With the means of acoustic forcing thermoacoustic instabilities can be detected. This thesis is going to be the base of the thermoacoustic investigation and aims to characterize the acoustic behaviour of the test rig without combustion. Therefore, analytical tools are used to create a network model of the test rig. This network model is then validated with experimental data and further refined.
Your Tasks
- Get to know the RQL test rig.
- Setting up the network model of the test rig.
- Validation of the network model with experimental data.
