Description:
Combustion instabilities are a major challenge in modern low-emission energy systems such as gas turbines and rocket engines. While industrial combustion systems often operate at pressures of 30 bar or higher, most academic studies are conducted at atmospheric pressure. As a result, the influence of operating pressure on the flame response remains poorly understood.The goal of this thesis is to investigate these pressure effects using high-fidelity CFD simulations.
Building on previous experimental investigations, you will simulate a laminar flame fueled with different blends of renewable fuels at varying operating pressures and analyze the results to identify the underlying physical mechanisms governing the flame response.
Scope of Work:
- Literature review on operating pressure effects on the flame response
- Set up the CFD domain, boundary conditions, initial conditions, and comp. mesh
- Computation of steady-state solutions and validation against experimental data
- Computation of the flame response to velocity forcing
- Analysis of the operating pressure on the flame shape and the flame response
Requirements:
- Basic knowledge of fluid mechanics and combustion theory
- Experience with CFD simulations, OpenFOAM experience is highly recommended
- Basic programming and post-processing skills, preferably with Python
- Good English or German language skills
