Velocity and pressure measurements in guide vane clearance gap of a low specific speed Francis turbine
(Journal article; Peer reviewed, 2016)In Francis turbine, a small clearance gap between the guide vanes and the cover plates is usually required to pivot guide vanes as a part of governing system. Deflection of cover plates and erosion of mating surfaces causes ... -
Ventilasjon av fotballhaller
(Master thesis, 2018)I nye bygg blir det stadig strengere krav til ventilasjon, både med tanke på luftkvalitet og energibruk. Fotballhaller har til nå falt under radaren med sine uoppvarmede areal og mangel på ventilasjon. Bygningstypen har ... -
Ventilasjon av klasserom
(Master thesis, 2008)Sammendrag Oppgaven kommer som et resultat av et fordypningsprosjekt i 2007 - Ventilasjonseffektivitet i rom og lokaler med store variasjoner i lufttilførselen. Oppgaven gikk ut på å sette seg inn i simuleringsprogrammet ... -
Ventilation design conditions associated with airborne bacteria levels within the wound area during surgical procedures: a systematic review
(Peer reviewed; Journal article, 2021)Background Without confirmation of the ventilation design conditions (typology and airflow rate), the common practice of identifying unidirectional airflow (UDAF) systems as equivalent to ultra-clean air ventilation ... -
Ventilation in low energy residences – a survey on code requirements, implementation barriers and operational challenges from seven European countries
(Peer reviewed; Journal article, 2020)This paper reports the results of an interview survey conducted among different stakeholders involved in design, installation and operation of residential ventilation in seven European countries. In total 44 interviews ... -
Ventilation systems and their impact on indoor climate and energy use in schools : studies of air filters and ventilation control

Ventilative cooling as a solution for highly insulated buildings in cold climate
(Peer reviewed; Journal article, 2015)One of the downsides of super insulated building envelopes is their facility to be overheated needing removal of excess heat. The removal of surplus heat is often done by mechanical cooling. However, energy consumption ... -
Ventilative cooling for schools and kindergartens
(Master thesis, 2014)As the building industry strives towards the goal of ZEB (zero emission/energy buildings), new and refurbished modern day buildings have to relate to ever increasing standards regarding energy efficiency and energy ... -
Ventilative cooling in Living Lab
(Master thesis, 2015)This thesis is a study of ventilative cooling in super insulated residential buildings with focus on thermal comfort and energy use. The case of the study is Living Lab, an approximately 100m2 detached residential building ... -
Ventilative Cooling of a Super Insulated Residential Building - Ventilasjonkjøling av superisolert bolig
(Master thesis, 2018)Passive cooling methods are preferred for super insulated, energy efficient buildings, to keep the energy consumption low. However, well insulated buildings are associated with longer cooling seasons, which means that air ... -
Ventilative cooling of Zero Emission Buildings (ZEB)
(Master thesis, 2017)Well-insulated buildings, like Zero Emission Buildings (ZEB), have a high occurrence of overheating even in cool climates. It is important to have cooling systems installed to achieve thermal comfort for the occupants of ... -
Ventilative Cooling Potential of the ZEB Laboratory
(Master thesis, 2021)Velisolerte bygninger, som Zero Emission Buildings (ZEB), utsettes for en høy forekomst av overoppheting i kjølesesongen. Kjøling blir nødvendig for å oppnå et godt termisk miljø, men mekanisk kjøling har et høyt energiforbruk ... -
Ventilering i svømmehall med nytenkende utforming av avtrekk
(Bachelor thesis, 2022)I denne oppgaven blir utfordringene ved å ventilere svømmehaller drøftet. Det blir presentert og diskutert en mulig løsning for å forbedre ventilering, folkehelse og inneklimaet i svømmehaller. Gjennom litteraturstudier, ... -
Verdien av en batteribank på campus Evenstad som nullutslippsområde
(Bachelor thesis, 2019)Klimagassutslipp fra bygninger trenger å reduseres for å hindre global oppvarming. En effektiv måte å gjøre dette på, er ved å etablere nullutslippsområder. Campus Evenstad er et pilotprosjekt som utvikles mot å bli et ... -
Verification of a Cartesian grid method for compressible flow over moving structures
(Master thesis, 2017)A simplified, low order finite volume Cartesian grid method for inviscid compressible flow over rigid, moving structures is developed and tested in two spatial dimensions to assess the treatment of the moving boundary and ... -
Verification of heat and mass transfer closures in industrial scale packed bed reactor simulations
(Journal article; Peer reviewed, 2018)Particle-resolved direct numerical simulation (PR-DNS) is known to provide an accurate detailed insight into the local flow phenomena in static particle arrays. Most PR-DNS studies in literature do not account for reactions ... -
