Optical investigation of NH3 and NH3/H2 flames in a turbulent combustion chamber
Optical investigation of NH3 and NH3/H2 flames in a turbulent combustion chamber
Ammonia and hydrogen are promising future fuels for reducing greenhouse gas emissions from large engines. Since the flame propagation of ammonia and hydrogen differs fundamentally from that of conventional fuels, this work aims to investigate the relevant combustion phenomena of ammonia and ammonia-hydrogen mixtures.
Target:
This master’s thesis aims to carry out high-speed schlieren measurements on the laminar and turbulent burning velocities of ammonia and ammonia/hydrogen mixtures in a turbulent combustion chamber at LEC. The optical data are to be evaluated and interpreted with regard to the special combustion properties of the new fuels (e.g. reactivity, turbulence-flame interaction, instabilities).
Tasks:
- Familiarization with combustion fundamentals and schlieren technology
- Commissioning of turbulent combustion chamber and measurement technology
- Performing schlieren measurements of the laminar and turbulent burning velocity of NH3 and NH3/H2 flames
- Evaluation of the image data on flame propagation
- Interpretation of schlieren results with regard to the combustion properties of future fuels
- Writing the master thesis
Starting date: By arrangement
Duration: Approximately 6 months
