Three-dimensional wake measurements
(Master thesis, 2010)The performance of a hot wire probe with three wires is investigated for two different flow cases. The wires are made of a platinum/rhodium alloy, and has a diameter of 5 micrometer. The three wires make a probe volume ... -
Thrust gas bearing analytical tool development
(Master thesis, 2014)Looking for a cheaper and low maintenance alternative to magnetic bearings, Statoil patented a new design for thrust gas bearings with honeycomb/hole-patterned surface. Honeycomb/hole-pattern surface on annular seals have ... -
Tidligfase vekt og kost estimering av offshore prosessutstyr
(Master thesis, 2015)The purpose of this work is to establish the basis of a methodology for quantifying process equipment, as a response to the different parameters which influence process design. Defining the process facility is one of the ... -
Tilpasning av LNG-prosess og -system til arktisk klima
(Master thesis, 2010)LNG-produksjon i arktisk klima åpner for høy prosesseffektivitet, men prosessen og utstyret må tilpasses en slik operasjon. Kraftproduksjonssystemet vil i tillegg dra fordel av lave temperaturer, men også her vil det være ... -
Tilrettelegging for deltakelse i et fleksibilitetsmarked
(Bachelor thesis, 2020)Det norske kraftnettet står i dag ovenfor utfordringer som økende elektrisitetsbehov, uregulerbar fornybar energiproduksjon, endringer i forbruksmønster og desentralisert energiproduksjon. Smartby-prosjektet +CityxChange, ... -
Tilstandsanalyse av vindturbiner ved bruk av SCADA data
(Bachelor thesis, 2023)Vindenergi er og fortsetter å være en essensiell del av kraftproduksjon globalt sett, og derfor er det viktig å redusere nedetid og vedlikeholdskostnader i vindparker. Kunnskap om årsakene til feil i en vind turbin hjelper ... -
Time evolution of uniform moment zones in a turbulent boundary layer
(Journal article; Peer reviewed, 2018)Time-resolved planar particle image velocimetry (PIV) was used to analyse the structuring of a turbulent boundary layer into uniform momentum zones (UMZs). The instantaneous peak detection method employed by Adrian et al. ... -
Time to rethink trophic levels in aquaculture policy
(Peer reviewed; Journal article, 2021)Aquaculture policy often promotes production of low-trophic level species for sustainable industry growth. Yet, the application of the trophic level concept to aquaculture is complex, and its value for assessing sustainability ... -
Time-dependent boundary conditions for multiphase flow
(Doktoravhandlinger ved NTNU, 1503-8181, Doctoral thesis, 2004)In this thesis a set of boundary conditions for multiphase flow is suggested. Characteristic-based boundary conditions are reviewed for single-phase flow. The problem of open-boundary conditions is investigated, and to ... -
Time-Dependent Effects of Glaze Ice on the Aerodynamic Characteristics of an Airfoil
