PhD position

deadline postponed


KTH Royal Institute of Technology, School of Engineering Sciences

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Project description

Third-cycle subject: Vehicle and Maritime Engineering

Two PhD positions are available within the EU funded Marie Sklodowska Curie Innovative Training Network POLKA (POLution Know-how and Abatement). Combustion of hydrogen from renewable sources is an emerging technology that can replace fossil fuels and thus provide carbon-neutral energy. The goal of POLKA is to solve serious technical problems, which are unique to hydrogen combustion: thermoacoustic instabilities and flashback. Thermoacoustic instabilities are large-amplitude pressure oscillations caused by an escalating interaction between the flame and acoustic waves; they tend to occur unexpectedly and cause major hardware damage. Flashback is the dangerous phenomenon of the flame propagating backwards into components not designed for high temperatures. The ultimate vision of POLKA is to create new physical insight and advanced simulation tools, so as to underpin the development of hydrogen-fuelled combustion systems (gas turbines, aero-engines, boilers furnaces, etc). The methods to be used are a combination of experiments, numerical simulations and analytical techniques. The projects at KTH focus on: Sound absorption mechanisms in micro-perforated plates with grazing flow and under hot conditions and Passive instability control by finned tube rows.
