Hydrodynamic modelling of physical habitat conditions for fish in the Ekso river near Flatekval
(Master thesis, 2018)In this study, a 2D hydrodynamic model HEC-RAS is used to simulate the flood inundation, water depths and flow velocities of the river reach in the Eksingedal watercourse near Flatekval in western Norway. The objectives ... -
Hydrodynamic optimization of bulk and tank ship hulls
(Master thesis, 2016)International shipping transports more than 80 percent of global trade. Traditionally bulk carriers have been built to minimize construction cost and maximize cargo-carrying capacity, neglecting hydrodynamic characteristics. ... -
Hydrodynamic Optimization of Trimaran Workboat Hulls
(Master thesis, 2017)The object of this master thesis was to perform an initial design optimization for a trimaran concept, with the goal of minimizing the hydrodynamic resistance for a speed of 30 knots. The thesis is written in cooperation ... -
Hydrodynamic optimization of wetland restoration measures at the Storelva river floodplain with its meanders and oxbow lakes in Southern Norway
(Master thesis, 2019)The “Fellesprosjektet Ringeriksbanen og E16” is an infrastructure project in the south of Norway connecting Oslo and shortening the travel time with the new housing and develop-ment area of Ringerike. For the connection ... -
Hydrodynamic performance of sail-assisted merchant vessels
(Master thesis, 2014)The main goal of this project was to explore the different physical effects that are involved when a ship is using the technology of wing sails as propulsion. The wing sails can provide a lot of thrust, but they also create ... -
Hydrodynamic rainfall-runoff modelling for flash floods in small and steep catchments
(Doctoral theses at NTNU;2024:261, Doctoral thesis, 2024)Global warming and climate change lead to more frequent and extreme weather events. These include sudden and intense rainfall and rising temperatures which cause flash floods. In steep terrains, flash floods with high-flow ... -
Hydrodynamic study of a moored fish farming cage with fish influence
(Doctoral theses at NTNU;2019:22, Doctoral thesis, 2019)The thesis deals with the influences of all components of the fish farming cage on the mooring loads, focusing on the influences of the fish school. First, the net cages with and without closed bottom were studied in ... -
Hydrodynamic Study of ROV (Remotely Operated Vehicle) Operations at Net-based Fish Farms
(Master thesis, 2021)Det er en tendens til at akvakultur flytter oppdrettssteder til stadig mer utsatte steder. Samtidig står industrien overfor problemer med brudd i garnstrukturer og følgelig fisk som rømmer. Utvikling av fjernstyrte kjøretøyer ... -
Hydrodynamic testing of wind-assisted cargo ships using a cyber–physical method
(Peer reviewed; Journal article, 2021)A novel empirical method to study wind-assisted cargo ships is presented. The physical ship model, including propulsion units, interacts in real-time with a numerical sail model during free-running tests. Loads from the ... -
Hydrodynamics of a flexible containment boom
(Master thesis, 2023)Denne masteroppgaven studerer hydrodynamikken til en fleksibel inneslutningsbom. En global modell basert på teori om kabelstrukturer ble utviklet for å estimere deformasjonene til en bomstruktur som møter strøm. Denne ... -
Hydrodynamics of a hydrofoil vessel with CP propellers
(Master thesis, 2020)Formålet med denne oppgaven har vært å ta for seg et hydrofoilfartøy i en ny kontekst, gitt de fordeler man i dag besitter teknologisk, med den hensikt å vurdere muligheter, fordeler og svakheter for montering av et ... -
Hydrodynamics of non-circular bluff bodies
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:302, Doctoral thesis, 2011)The present doctoral thesis is devoted to investigate and study the complex three-dimensional wake flow dynamics from different types of non-circular bluff bodies. The bluff body configuration considered in this work is ... -
Hydrodynamisk studie av en 2D geometri lik fisk under bevegelse
(Master thesis, 2019)Denne masteroppgaven viser resultater fra simuleringer av en NACA0012 foil i statiske og bevegeligetilfeller. En innledende studie har hatt som formål å simulere en statisk foil og å få til resultatertilsvarende det som ... -
Hydrodynamisk studie av flytende vindturbiner i ekstreme forhold
(Master thesis, 2019)En økende etterspørsel etter fornybare energiressurser har støttet opp under nye studier og videre utvikling av offshore flytende vindturbiner på dypt vann. Utfordringer knyttet til denne teknologien er sterk vind og høye ... -
Hydrodynamisk teori for bølgjekraftverk: forelesningsnotat

Hydrodynamiske beregninger med bølgeoverflater
(Master thesis, 2011)Innledningsvis ble noe av det teoretiske grunnlaget for oppgaven gitt. De viktigste antagelsene var at strømningen er isotermisk og at fluidene er antatt å være inkompressible. Videre er det gått igjennom hvodan man setter ... -
Hydrodynamiske beregninger vha GPU
(Master thesis, 2010)Om man skal gjøre prediksjoner av hydrodynamiske egenskaper til større marine strukturer i dag, er den vanligste måten fremdeles modellforsøk, empiri og lineærteori. Viskøse CFDsimuleringer ved hjelp av RANSmetoder har ... -
Hydrodynamiske utfordringer av flytende vindturbiner i grunnere dybder
(Master thesis, 2019)Idag er alle flytende vindturbiner installert på dypt vann(>100 m). Nærhet til kyst og tilgjengelige områder, gjør derimot også installasjon på vanndybder fra 50-70 m lønsomt. Men, ved denne vanndybden oppstår det tekniske ... -
