Design of Airfoil for downwind wind turbine Rotor
(Master thesis, 2009)This thesis is on the design of an airfoil for a downwind wind turbine rotor with thin flexible wings, for offshore floating conditions. It has been suggested that such a system would to be lighter, simpler and allow for ... -
Development of Calculation Model for Heat Exchangers in Subsea Systems
(Master thesis, 2010)Subsea processing can make production from otherwise unprofitable fields profitable. In subsea processing controlled cooling of the process fluid will often be required. Robust and simple solutions are desirable in subsea ... -
Development of new heat pump cloth drum dryer with CO2 as working fluid
(Master thesis, 2011)Since early the early 20th century the electrical tumble dryer became an appliance to dry clothes. During many years of improvements different configurations to solve issues on decreased drying time and more energy efficient ... -
Development of vehicle participating in Shell Eco Marathon 2008: Integration of the Nexa fuel cell power module used in the vehicle propulsion system
(Master thesis, 2008)A commercially available fuel cell has successfully been implemented in a fuel efficiency vehicle which participated in the French 2008 event of the Shell Eco-Marathon. To do so the cell was tested, so an optimal utilization ... -
Dimensioning Loads for a Tidal Turbine
(Master thesis, 2011)The main dynamic loads on a tidal turbine are due to the tidal current variation, turbulence, wave-current interaction and wake from the tower and upstream turbines. The design of the turbine is highly dependent on the ... -
Dynamisk simulering av systemløsninger for kuldeanlegg i supermarked
(Master thesis, 2011)Energibruk i supermarkeder er blant de høyeste innefor bygningssektoren i Norge. Norske supermarkeder har typisk et årlig energibehov på mellom 400 og 600 kWh/m^2 . Opp mot 50 % av dette totale energibehovet går til ... -
Eco-efficiency of Power Generation Options at a Refinery
(Master thesis, 2008)This master thesis is investigating environmental performance of different alternatives for Combined Heat and Power (CHP) production from Natural Gas (NG) at Mongstad oil refinery. An important objective is to evaluate CHP ... -
Effekt av overflateruhet på diffusorstrømning
(Master thesis, 2011)Effekt av overflateruhet på diffusorstrømningMasteroppgave av Roy-Andre Midtgård, med veileder professor Per-Åge Krogstad.Formålet med dette prosjektet er å studere effekten av overflateruhet på et turbulent grensesjikt ... -
Efficiency measurements at Vessingfoss power station
(Master thesis, 2007)A measurement of the hydraulic turbine efficiency at the Vessingfoss hydro power station by the thermodynamic method has been attempted, but has not given the desired results. Two problems have been encountered. The high ... -
Eksperimentell oppgave relatert til Gibson-metoden
(Master thesis, 2008)Det er kjent at Gibsons metode gir store avvik ved lave gjennomsnittshastigheter og korte avstander mellom måletverrsnittene, noe som gjør metoden lite egnet i mange kraftverk. Våren 2008 ble det etablert en testrigg i ... -
Energibruk og energiutnyttelse ved Kårstø gassprosesseringsanlegg
(Master thesis, 2007)Hensikten med denne masteroppgaven har vært å studere energiforbruket på Kårstø gass- prosesseringsanlegg. Økende energipriser og strengere miljøkrav fører til et økende fokus på energibesparende tiltak. Denne rapporten ... -
Energibruk og inneklima i lavenergi kontorbygning
(Master thesis, 2011)I september 2009 tok KLP Eiendom i bruk kontorbygget i Professor Brochs gate 2 (PB2) i Teknobyen i Trondheim. Denne bygningen har klimaskjerm og tekniske løsninger som tilsier langt lavere energibruk enn dagens forskriftskrav. ... -
Energibruk og inneklima i passiv- og lavenergihus
(Master thesis, 2010)Det er gjennomført målinger av energibruken til ulike formål i fem leiligheter i Løvåshagen borettslag i Bergen. Tre av leilighetene er av lavenergistandard, mens de to siste er av passivhusstandard. Hovedmålsetningen med ... -
