Optical investigation of NH3 and NH3/H2 flames in a turbulent combustion chamber

https://www.lec.at/job-entries/optische-untersuchung-von-nh3-und-nh3-h2-flammen-in-einer-turbulenten-brennkammer/?lang=en

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

https://www.lec.at/job-entries/experimentelle-charakterisierung-der-stroemungsbedingungen-in-einer-turbulenten-brennkammer/?lang=en

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…

PhD position with research focus on exhaust gas aftertreatment for large ammonia engines (m/f/d)

https://www.lec.at/job-entries/phd-position-with-research-focus-on-exhaust-gas-aftertreatment-for-large-ammonia-engines-m-f-d/?lang=en

Ammonia is currently the subject of increased interest as potential renewable energy carrier and alternative fuel for large internal combustion engines. However, the use of ammonia as a fuel brings new challenges not only regarding the combustion concept but also for the exhaust gas aftertreatment. In order to meet the increasingly demanding requirements for minimum pollutant and greenhouse gas emissions…

Development of a virtual pressure transducer for engine control

https://www.lec.at/job-entries/development-of-a-virtual-pressure-transducer-for-engine-control/?lang=en

For environmentally sound, efficient and robust large engines, it is essential to have a detailed knowledge of the combustion process. In-cylinder pressure transducers are often applied in advanced combustion control systems. This allows each cylinder to be operated efficiently while avoiding anomalies such as knocking or misfiring. Since high-quality cylinder pressure transducers come with a limited lifetime and at a…
