Job Description Summary

We present a unique opportunity for a dedicated master's student at TU Berlin to undertake a challenging master's thesis project with our combustion team at the Advanced Aviation Technology Center of Excellence. The focal point of this project lies in investigating the Precessing Vortex Core (PVC), a dominant flow structure prevalent in swirled fuel injection systems, among other configurations. These coherent structures have the potential to interact with the flame, causing fluctuations in heat release. In a worst-case scenario, these fluctuations can couple with an acoustic mode of the combustion chamber, leading to significant pressure variations that must be mitigated. The master's thesis project will leverage a cutting-edge analytical tool for Linear Mean Field Analysis (LMFA), a method in the realm of numerical fluid mechanics. The primary objective of this study is to further advance the LMFA toolset to ultimately advance our understanding of the PVC's nature and to develop effective control measures.

This full-time position is limited to 6 months with a start-date as soon as possible.
