Experimental and numerical investigation of a moored floating structure in waves
(Master thesis, 2019)Floating structures play a major role in a wide range of traditional industrial branches as well as in recently developing sectors such as renewable energies. An accurate prediction of the movement of floating structures ... -
Experimental and Numerical Investigation of One-Dimensional Infiltration into Unsaturated Soil
(Chapter, 2021)Infiltration characteristics of an unsaturated soil are of interest in both seepage and stability analyses and should be evaluated carefully. In this study, a new large-scale one-dimensional infiltration column test setup ... -
Experimental and Numerical Investigation of Sloshing under Roll Excitation at Shallow Liquid Depths
(Journal article; Peer reviewed, 2017)This paper investigates sloshing at shallow-liquid depths in a rectangular container by using experimental and numerical methods. A motion platform is used to perform a prescribed periodic rotational motion to excite the ... -
Experimental and Numerical Investigations of Dynamic Positioning in Discontinuous Ice
(Doctoral thesis at NTNU;2015:329, Doctoral thesis, 2015)This thesis studies dynamic positioning (DP) operations of a conceptual Arctic drillship in discontinuous sea ice conditions. The stationkeeping behaviour of the vessel under the influence of dynamic ice actions is ... -
Experimental and Numerical Investigations of Ice-Structure Interaction
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:26, Doctoral thesis, 2009)Ice interacting with offshore structures is of major engineering concern in areas where human activities and (seasonal) sea ice coexist. This thesis deals with experimental as well as numerical investigations of (level) ... -
Experimental and numerical investigations of the water surface profile and wave extrema of supercritical flows in a narrow channel bend
(Journal article; Peer reviewed, 2024)Supercritical flows in channel bends, e.g., in steep streams, chute spillways, and flood and sediment bypass tunnels (SBTs), experience cross-waves, which undulate the free surface. The designs of these hydraulic structures ... -
Experimental and Numerical Studies of Moored Ships in Level Ice
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:14, Doctoral thesis, 2011)Moored ships are believed to be feasible for marine operations in ice-covered waters. A variety of ice features, such as broken ice, level ice, ridged ice and icebergs, will pose potential challenges with respect to design ... -
Experimental and numerical studies related to failure of first-year ice ridges against fixed vertically sided structures
(Doctoral theses at NTNU;2019:192, Doctoral thesis, 2019) -
Experimental and Numerical Study of Waves Breaking Over a Submerged Three-Dimensional Bar
(Peer reviewed; Journal article, 2022)Depth-induced breaking is the major wave transformation process in coastal waters that significantly influences the wave energy that eventually reaches the coastline. Most studies of depth-induced wave breaking focus on ... -
Experimental basin- and laboratory-scale studies related to ice ridges, rubble accumulations and freeze-bonds
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:256, Doctoral thesis, 2011) -
Experimental hydraulics on fish-friendly trash-racks: an ecological approach
(Journal article; Peer reviewed, 2018)The obstruction of fish migratory routes by hydroelectric facilities is worldwide one of the major threats to freshwater fishes. During downstream migration, fish may be injured or killed on the trash-racks or in the ... -
An experimental investigation into moisture-induced expansion of plasters
(Peer reviewed; Journal article, 2015)This paper presents an experimental study on moisture-induced expansion of selected plasters. Contactless measurement is introduced and a coefficient of moisture expansion for different building plasters is established. ... -
Experimental Investigation of an Inclined, Floating Breakwater with a Porous design and Bio-enhancing features
(Master thesis, 2022)Verden går i møte risikoer ved den globale oppvarmingen som er betydelig større enn det som tidligere er beskrevet, herunder økning av sjønivå og ekstreme værfenomener. Klimaendringene har også medført betydelige og ... -
Experimental investigation of flow pattern over a fully developed bed at a 60° river confluence in large floods
(Peer reviewed; Journal article, 2022)River confluences have a complex flow and sedimentation pattern that have vital influences on the hydraulic and bed morphology of river reach and the surrounding area. Confluences can be observed in waterways with various ... -
Experimental investigation of ice loads on vertical and slope offshore structures
(Master thesis, 2020)An experiment was carried out to study the ice loads of level ice and ridge on the vertical and slope structures. The prototype of the model is the lighthouse Nordströmsgrund, which is a vertical structure and locates in ... -
Experimental investigation of simultaneous nitrification-denitrification and phosphorus removal in pilot-scale sequencing batch moving bed biofilm reactors (SB-MBBRs)
(Journal article; Peer reviewed, 2024)Sequencing batch moving bed biofilm reactors have been widely used in commercial wastewater treatment facilities for organic carbon and nitrogen removal. However, these reactors can remove low phosphorus (P) levels. ... -
Experimental Investigations of Aerogel-Incorporated Ultra-High Performance Concrete
(Journal article; Peer reviewed, 2015)Improvements to concrete will have a large impact in the construction and building sector. As the attention is drawn towards energy-efficient and zero emission buildings, the thermal properties of concrete will be important. ... -
