The Institute of Propulsion Technology makes highly efficient engines even more powerful and conducts research on future propulsion solutions for climate‑neutral aviation. Our work spans a broad spectrum of gas‑turbine technology. What makes us unique: we combine expertise in components, computational simulation and experiments up to high technology‑readiness levels under one roof, giving us a holistic understanding of the complete turbomachine.
What you can expect
In the Numerical Methods department we are building a numerical test‑rig for simulating turbulent flow in engines. For this we run time‑ and space‑resolved high‑resolution simulations on high‑performance computers.
In this master’s thesis you will investigate the laminar‑to‑turbulent transition under the influence of shock‑boundary‑layer interaction in a trans‑sonic high‑pressure turbine blade row. The starting point is an existing data set of high‑fidelity simulations at several operating points. You will analyse these data for the underlying physical mechanisms and derive recommendations for follow‑up simulations in order to study the dominant parameters that affect the transition process more closely.
Your responsibilities
- Familiarisation and literature review on the numerical methods used, Large‑Eddy Simulation (LES) in turbine blade rows, and laminar‑to‑turbulent transition in the presence of shock‑boundary‑layer interaction
- Analysis of the existing time‑resolved data sets with respect to the transition process
- Development of recommendations for investigating the influence parameters on transition in the presence of shock‑boundary‑layer interaction
- Execution and analysis of high‑fidelity CFD simulations to further examine the influence parameters on transition
- Documentation and presentation of the results
What you bring
- Very good to good grades in an advanced engineering or natural‑science course
- Knowledge in the following areas: fluid mechanics, gas dynamics, numerical flow simulation (CFD)
- Independent and motivated way of working
We offer
DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified.
We look forward to getting to know you!
