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 ... -
Hydroelastic slamming response in the evolution of a flip-through event during shallow-liquid sloshing
(Journal article; Peer reviewed, 2014) -
Hydroelastic slamming response in the evolution of a flip-through event during shallow-liquid sloshing
(Journal article; Peer reviewed, 2014)The evolution of a flip-through event [6] upon a vertical, deformable wall during shallow-water sloshing in a 2D tank is analyzed, with specific focus on the role of hydroelasticity. An aluminium plate, whose dimensions ... -
Hydroelasticity analysis of a vessel-shaped fish cage under incident, diffraction and radiation wave fields
(Peer reviewed; Journal article, 2023)Vessel-shaped fish cages are promising large aquaculture structures developed in recent years, with an overall length of nearly 400 m. In this paper, a coupled hydroelasticity model of a vessel-shaped fish cage is used to ... -
Hydroelectric Real Options: A Structural Estimation Approach
(Master thesis, 2011)Structural estimation is an important technique in analyzing economic data. Unfortunately, it is often computationally expensive to implement the most powerful and efficient statistical methods. One such method is the ... -
HydroFy Final Report: Recent developments in European power market design – with implications for hydropower
(HydroCen Rapport;42, Research report, 2023)The ongoing energy transition is profoundly transforming power systems. The change of paradigm that is taking place in the power sector leads to questioning the current market design. As reservoir hydropower is a renewable, ... -
Hydrogel beads from marine polysaccharides: Investigation of bead formulations for use in cell encapsulation
(Doctoral theses at NTNU;2022:287, Doctoral thesis, 2022)Sykdommer som type 1 diabetes og akutt leversvikt kan behandles med transplantasjon. Et mindre omfattende inngrep kan gjøres ved bruk av isolerte celler fremfor hele organer. Likevel krever transplantasjon immundempende ... -
Hydrogen and Wet Gas Compressor Analysis
(Master thesis, 2020)Verdens energiproduserende industri står overfor flere utfordringer i sin søken etter å minimere ut- slippene av drivhusgasser. Nyvinninger i lav- og nullutslipps energiproduksjon og forventninger om videre innovasjon ... -

Hydrogen assisted crack growth in iron: a simulations approach
(Doctoral theses at NTNU;2021:32, Doctoral thesis, 2021)Hydrogen enhances crack growth, limiting the lifetime of industrial components. Despite the abundance of research into hydrogen enhanced crack growth and its proposed mechanisms, none of the models can explain all the ... -
Hydrogen cyanide, a key plant defense, as a potential driver of root-associated nematode communities along urbanization gradients
(Peer reviewed; Journal article, 2023)Introduction: Plant chemical defenses can influence the distribution, community composition, and abundance of soil biota. Urbanization plays a key role in shaping soil biotic communities either directly through changes in ... -
