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
(Others, 1980) -
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 ... -
Hydroelastic Analysis of Flexible Wedges
(Master thesis, 2013)This thesis presents a simulation method for analyzing the coupled water entry problem of elastic bodies. The water entry problem is investigated using the software STAR CCM+ for computational fluid dynamics and Abaqus for ... -
Hydroelastic behaviour of a structure exposed to an underwater explosion
(Journal article; Peer reviewed, 2015)The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large ... -
Hydroelastic response of a flexible spar floating wind turbine: Numerical modelling and validation
(Journal article; Peer reviewed, 2023)This study examines the hydroelastic response of a large floating wind turbine (FWT) through coupled numerical analysis. Four numerical models with different levels of complexity in the hydrodynamic and structural modelling ... -
Hydroelastic response of a submerged structure to an underwater explosion
(Chapter, 2014)The use of composite structures in offshore engineering has revamped the problem of Fluid Structure Interaction (FSI) during underwater blasts because they enhance the FSI effect and increase the shock resistance of ... -
Hydroelastic response of concrete shells during impact on calm water
(Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
