Tunnel under Hardangervidda: Vurdering av drivemetode og traséplassering
(Master thesis, 2013)Hensikten med denne masteroppgaven var å belyse sentrale aspekter ved etablering av en tunnel under Hardangervidda. For å gjøre dette har denne rapporten gått gjennom, utarbeidet og fremstilt et helhetlig grunnlag nødvendig ... -
Tunnelbyggetid for vann- og frostsikring
(Master thesis, 2022)Byggetid for tunneler har i det siste tiåret ført til økende grad av uenighet og tvister som til sammen utgjør en betydelig verdi. Et samarbeidsforum bestående av ulike byggherrer, entreprenører, NTNU og Entreprenørforeningen ... -
Tunnelbyggetid ved rystelsesbegrensninger
(Bachelor thesis, 2021)Ved bygging av en tunnel må det noen ganger tas hensyn til eksisterende konstruksjoner som gjør at metoden for tunneldrivingen må endres. Gjennombrytning ved hjelp av sprengning medfører at vibrasjoner kan gjøre skade på ... -
TUNNELING ASPECTS OF THE WATERWAY SYSTEM AND STABILITY ASSESSMENT OF THE POWERHOUSE CAVERN FOR THE MINAS-SAN FRANCISCO HPP
(Master thesis, 2018)The future trend of energy supplies is gradually moving from fossil fuels to renewable and sustainable energy sources. In this context, hydropower is one of the best options to supply the base load and meet the energy ... -
Tunnelkonsept for Fornebubanen - Bør Fornebubnanen fremføres i ett eller to tunnelløp
(Master thesis, 2015)Fornebubanen er en ny T-banelinje som planlegges mellom Fornebu i Bærum og Majorstuen i Oslo, med nye stasjoner i Bærum, på Lysaker, på Vækerø og på Skøyen. Banen planlegges i sin helhet under bakken med midtplattformer ... -
Tunnelling challenges in Nepal
(Chapter, 2004)Nepal is a landlocked mountainous country with a population of approximately 23 millions. Being steep in topography and having many rivers originating from the glaciers of the Himalaya, Nepal has been gifted in the field ... -
Tunnelstein som ressurs
(Master thesis, 2020)I Noreg vert det kvart år teke ut om lag 19 millionar tonn stein frå driving av tunnelar. Samtidig minkar norske grus- og sandførekomstar, og transportavstandar for byggeråstoff aukar. Mengda tunnelstein frå norske ... -
Turbo-compressors for R-718: Experimental evaluation of a two-stage steam compression cycle
(Chapter, 2019)Water (R-718) is a safe and energy-efficient refrigerant. Mechanical vapour recompression (MVR), an open-loop heat pump using R718, can significantly reduce the energy consumption for steam-heated processes like drying, ... -
Turbomachinery design for Rankine cycles in waste heat recovery applications
(Master thesis, 2017)Rankine Cycles are an effective and efficient manner to convert waste thermal energy into power. Numerous fluids can be used in Rankine cycles, including water, hydrocarbons, hydrofluorocarbons, siloxanes, alcohols or even ... -
Turbophoresis in forced inhomogeneous turbulence
(Journal article; Peer reviewed, 2018)We show, by direct numerical simulations, that heavy inertial particles (characterized by Stokes number St) in inhomogeneously forced statistically stationary isothermal turbulent flows cluster at the minima of mean-square ... -
Turborundkjøring som erstatning av dagens rundkjøring i Leirgrovvika
(Master thesis, 2018)Krysset i Leirgrovvika er utformet som rundkjøring. Krysset knytter europa- og fylkesveg, via en trearmet rundkjøring. Geografisk ligger rundkjøringen i et relativt flatt terreng. Dette er første krysset som blir brukt av ... -
Turbulence measurements with fixed and floating profiling wind lidar
(Doctoral thesis, 2020)Knowledge about turbulence in the wind helps estimate and optimize the profitability of wind turbines. Light detection and ranging (lidar) is a cost-efficient, flexible, and accurate remote sensing technology for measuring ... -
Turbulence modeling of transverse flow on ship hulls in shallow water
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:174, Doctoral thesis, 2010)The hydrodynamic forces acting on a ship that travels in restricted water vary greatly with water depth and the geometry of the ship hull. This will affect the ship maneuverability in terms of various flow effects like for ... -
Turbulence Modelling of the Flow Around a Prolate Spheorid
(Master thesis, 2018)In numerous engineering disciplines, including naval and offshore engineering, the accurate prediction of turbulent flows is essential for cost-efficient and safe designs. For industrial applications, the turbulence must ... -
Turbulent channel flow of generalized Newtonian fluids at a low Reynolds number
(Peer reviewed; Journal article, 2021)Several studies concerning the turbulent pipe flow of generalized Newtonian (GN) fluids may be found in the literature, but not for channel flow, although that has been extensively studied for other types of non-Newtonian ... -
Turbulent Couette–Poiseuille flow with zero wall shear
(Journal article, 2017)A particular pressure-driven flow in a plane channel is considered, in which one of the walls moves with a constant speed that makes the mean shear rate and the friction at the moving wall vanish. The Reynolds number ... -
Turbulent flow simulations at higher Reynolds numbers
(Doctoral theses at NTNU;2019:52, Doctoral thesis, 2019)This thesis presents recent advancements in direct numerical simulations of bluff body wake flows. The flow around a circular cylinder without and with special fairings have been studied, and the effect of boundary conditions ... -
