A fully automated multi-disciplinary design optimization procedure for a Francis turbine runner has been developed in a previous task of the Horizon2020-HydroFlex project. The design optimization was limited to blade design, with the goal of improving the hydraulic efficiency and torque, and...
... The paper presents the work of the Norwegian engineer Ægidius Elling (ref. Figure 1), from his gas turbine patent in 1884 to the first gas turbine in the world producing net power in 1903. It traces the subsequent patents, until his final experiments in 1932. Focus is placed on an engineer with a...
... “Innovative reactors” (based on chemical looping, membrane separation or sorption-enhanced processes) in power processes for CO2 capture appear to behave in such a way that some unconverted fuel could remain in the captured CO2-rich stream. This has the double drawback of adding impurities to the...
In order to be able to compare and possibly rank different technologies for CO2 capture, and different means of integrating novel process units into power cycles with CO2 capture, it is vital to apply a consistent benchmarking methodology. A benchmarking will then provide a snapshot of the...
Rapporten gjør en etterevaluering av en investering på 1,7 milliarder (løpende kroner) i nytt togradiosystem (GSM-R) i Norge i perioden 2003-2008. Kriteriene er produktivitet i utbyggingsfasen, effekter av investeringen (måloppnåelse), ytterligere virkninger, fortsatt relevans, løsningens...
The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative computed tomography (CT) of an OSAS patient, the pre- and post-operative...
The CCS Midt-Norge project phase 1 has been a collaboration between Franzefoss Minerals, Statkraft Varme, Elkem Thamshavn, Wacker Holla Metall, Equinor Tjelbergodden and SINTEF. CO2 emissions from the industries in the project are around 1.5 Mt/year. Power consumption for capturing and liquefying...
Carbon Capture and Storage (CCS) and Carbon Capture Utilisation and Storage (CCUS) are increasingly vital in urban sustainability agendas for their role in mitigating climate change. CCS focusses on capturing CO2 emissions from industrial and energy-related sources and storing them permanently...
It is stated by the International Energy Agency (IEA) that in the long term, "completely eliminating fossil fuels in transport and industry without resorting to hydrogen may be hard to achieve". (IEA, 2012). Hydrogen production from fossil fuels, when applying CO2 capture and storage (CCS) may be a...
Over the past decade there has been a tremendous research activity in the field of CO2 capture. In 2010, the European Technology Platform for Zero Emission Fossil Fuel Power Plants (ZEP) published a report entitled "Recommendations for research to support the deployment of CCS in Europe beyond...
Integrated Gasification Combined Cycle (IGCC) power plants with CO2 capture are expected to form an important part of a future carbon constrained energy scenario. As with all capture routes, research efforts related to IGCC have been concentrated on minimizing the energy penalty of the capture...
Post-combustion capture from power plants may offer an opportunity for power generation where the CO2 capture unit can be shut down in periods, in order to respond to short periods of high electric power demand in the power grid. As the CO2 capture unit is shut down, the power output from the power...
In this master thesis, a patient specific computational fluid dynamics (CFD) \nomenclature{CFD}{Computational Fluid Dynamics} study has been done on the air flow in the human upper airways before and after surgical intervention. The patient studied is a 67 years old man who went from having moderate...
