Validation of a Zonal Model to Capture the Detailed Indoor Thermal Environment of a Room Heated by a Stove
(Chapter, 2019)Using wood stoves is a common space-heating strategy in the Nordic countries. Currently, the lowest available nominal power of wood stoves is significantly oversized compared to the design space-heating load of highly-insulated ... -
Validation of a Zonal Model to Capture the Thermal Stratification in a Room Heated by a Stove
(Chapter, 2018)Using wood stoves is a common space-heating strategy in the Nordic countries. The power oversizing of a stove for a given building might deteriorate the indoor thermal environment, for instance with large thermal stratification. ... -
Validation of dynamic models of the thermal systems of swimming pools
(Master thesis, 2020)Svømmehaller er komplekse bygg som stiller høye krav til både bygningskropp og tekniske systemer. Et velfungerende ventilasjonsaggregat med optimal styring av temperatur- og fuktkontroll er svært viktig for å skape et godt ... -
Validation of the real-time-response ProCap measurement system for full field wake scans behind a yawed model-scale wind turbine
(Journal article; Peer reviewed, 2018)For an accurate prediction of the complex flow conditions in wind farms, model scale wake flow measurements represent important references in well-defined boundary conditions. State-of-the art flow measurement techniques ... -
Validation of Wet Gas Surge Phenomena
(Master thesis, 2012)AbstractIn order to utilize the fossil resources on the Norwegian continental shelf, technology and expertise have proven to be of great importance and hence, essential for further exploration and development of new ... -
Validering av våtgassytelse
(Master thesis, 2013)En trykkøkning vil gi gassreservoar økt produksjonsrate eller forlenget levetid, i noen tilfeller også begge deler. Subsea-kompresjon kan være et kostnadseffektivt alternativ til å installere kompresjonen ombord på et ... -
Valorisation of Napier Grass and Agricultural Residues via Pyrolysis – A Kinetic Study
(Peer reviewed; Journal article, 2022)Thermal pyrolysis of Thai Napier grass, cassava stalk and rice straw were studied thermogravimetrically, which was followed by a kinetic analysis assuming multiple kinetic schemes and a distributed activation energy model ... -
Value of green hydrogen when curtailed to provide grid balancing services
(Peer reviewed; Journal article, 2022)This paper evaluates the potential of grid services in France, Italy, Norway and Spain to provide an alternative income for electrolysers producing hydrogen from wind power. Grid services are simulated with each country's ... -
van der Waals induced ice growth on partially melted ice nuclei in mist and fog
(Journal article; Peer reviewed, 2023)Ice nucleation and formation play pivotal roles across various domains, from environmental science to food engineering. However, the exact ice formation mechanisms remain incompletely understood. This study introduces a ... -
Vannbehandling i lukkede energianlegg
(Master thesis, 2024)De aller fleste nye bygg i dag bygges med en form for vannbårent distribusjonssystem og som følge at manglende vedlikehold og vannbehandling, sliter mange med driften av disse anleggene. I 2023 kom veiledningen «Vannbehandling ... -

Vapor-liquid equilibrium data for the carbon dioxide and nitrogen (CO2+N2) system at the temperatures 223, 270, 298 and 303 K and pressures up to 18 MPa
(Journal article; Peer reviewed, 2015)A new setup for the measurement of vapor-liquid phase equilibria of CO2-rich mixtures relevant for carbon capture and storage (CCS) transport conditions is presented. An isothermal analytical method with a variable volume ... -
Vapor-liquid equilibrium data for the carbon dioxide and oxygen (CO2 + O2) system at the temperatures 218, 233, 253, 273, 288 and 298 K and pressures up to 14 MPa
(Journal article; Peer reviewed, 2016)Accurate thermophysical data for the CO2-rich mixtures relevant for carbon capture, transport and storage (CCS) are essential for the development of the accurate equations of state (EOS) and models needed for the design ... -
Vapor-liquid equilibrium measurement data for the two binary systems carbon dioxide + nitrogen and carbon dioxide + oxygen
(Doctoral thesis at NTNU;2016:118, Doctoral thesis, 2016)This thesis presents new, accurate, isothermal vapor-liquid equilibrium (VLE) measurement data for the two binary systems carbon dioxide and nitrogen (CO2+N2) and carbon dioxide and oxygen (CO2+O2). These measurements ... -
Variability of building energy performance at a scale: conformity of predictive and synthesis with explanatory modelling practices
(Doctoral theses at NTNU;2022:239, Doctoral thesis, 2022)Throughout its existence, humankind invented countless means and practices to design, construct and equip buildings. The number of ways to use these buildings, with or without strictly following their initially intended ... -
Variable speed operations of Francis turbines
(Master thesis, 2019)Den økende andelen av uregulerbar kraftproduksjon, som vind og sol, blir det stadig viktigere å ha mer pålitelige energikilder for å tilfredsstille etterspørselen av et varierende strømforbruk.Vannkraft kan brukes til dette ... -
Variable-speed operation and pressure pulsations in a Francis turbine and a pump-turbine
