Investigation of ammonia oxidation reaction mechanism including formation and reduction of nitrogen oxides and nitrous oxide
Ammonia has great potential as a carbon-free alternative to fossil fuels in the marine sector. In order to minimize the emissions of NOx, unburned NH3 and N2O from the exhaust gas of a new type of ammonia engine, a better understanding of the reaction mechanisms is required.Target: The aim of the master thesis is to develop a 1D model for…
Development of a differentiable code for solving flamelet equations
One possible modeling approach to simulate turbulent flames are so-called flamelet-based models. An accurate and yet computational efficient approach is to precompute the underlying flamelet equation and integrate the solution via look-up tables into CFD simulation environments. Target: In this master’s thesis, a code to solve flamelet equations and to generate look-up tables for turbulent combustion simulation is aimed to…

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…
Experimental characterization of the flow conditions in a turbulent combustion chamber
The turbulent combustion behavior of future fuels such as ammonia and hydrogen differs fundamentally from that of conventional fuels and will therefore be investigated in fundamental studies in a new turbulent combustion chamber at LEC. For this, the flow conditions in the combustion chamber are to be characterized in advance.Target: Fans generate an almost homogeneous, isotropic turbulence field with a…
Roadmap towards robust hydrogen combustion
https://www.lec.at/news-entries/lec-publication-towards-robust-hydrogen-combustion/?lang=en
The paper “Towards Robust Hydrogen Combustion: Precise Lube Oil Consumption Measurement as an Enabler for Tackling Pre-Ignition” focuses on one of the central challenges in the development of hydrogen combustion engines: the reduction of pre-ignition through precise lube oil consumption measurement.
