Energy and environmental technologies
The research group energy and environmental technologies works on a wide variety of energy-related topics such as alternative fuels, waste heat recovery, hybrid propulsion systems, energy production and conversion processes as well as system analysis.
Our lab and testing facilities include amongst others small compression and spark ignition engines, a Stirling engine, a biomass pyrolysis and gasification system as well as a basic set of measurement and analysis equipment.
Please check this website for more information about the solar lab.
In addition, several simulation and calculations tools from 3D CFD to process design software are being used.
We are using the following tools: StarCCM+, Ricardo WAVE, Ricardo IGNITE, TRNSYS and Sage of Athens, as well as self-developed code to investigate combustion and flow processes, hybrid propulsion systems (evaluation of conventional and alternative propulsion technologies), composition of syngas from biomass gasification and waste heat recovery potential with organic Rankine cycles.
The members of the research group, without this being a requirement to join the group, are in a varying degree involved with either the bachelor or master (together with UiB) courses in energy. Meetings and / or seminars are usually typically closely connected to presentations of bachelor and master theses.
Collaborators from industry, academia and the public sector are welcome both as project partners, sponsor of bachelor and master theses as well as presenters and guest lecturers.
