PhD position on combustion instabilities of hydrogen flames
The goal of this research is to investigate turbulent hydrogen-air combustion at elevated pressure. This research is relevant for decarbonizing key technologies for power generation and aircraft propulsion by means of hydrogen combustors. The position is financed by an ERC Synergy Grant (project HYROPE).
The small-scale turbulence-chemistry interaction and the large-scale hydrodynamic and thermoacoustic stability of propagating and autoigniting hydrogen-air flames must be understood for the development of hydrogen combustion technologies. In particular, the influence of the pressure on the combustion physics of these flames needs to be elucidated.
This research work will combine experiments and modeling. The experimental research will be performed on a lab-scale, high-pressure test facility. Experimental techniques for fluid mechanics, combustion and acoustics will be used, including laser-based optical diagnostics. The modeling work will consist in the development of analytical low-order models of the combustion instabilities, and in large eddy simulations of the compressible Navier-Stokes equations.
You are expected to have a MSc degree in Mechanical Engineering or Physics. Your MSc thesis is related to one or more of the following disciplines: fluid mechanics, combustion, acoustics. Ideally, you would be available for a start in October 2024.
We are looking for highly motivated, committed, and creative individuals, able to work in a team and with excellent communication skills. Working in a top-level research environment with advanced laboratory infrastructure, the candidate will have a unique opportunity to develop her/his research abilities.
