Experimental and numerical investigation of a freefall wedge vertically entering the water surface
(Journal article; Peer reviewed, 2015)Experiments and numerical methods are developed to investigate the water entry of a freefall wedge with a focus on the evolution of the pressure on the impact sides (the side contacting water) and the top side (the dry ... -
Experimental and numerical investigation of a marine biomass slurry
(Master thesis, 2021)Det er en betydelig andel restråstoff som ikke blir fullstendig utnyttet. Noe av dette restråstoffet kan prosesseres til høy-verdiprodukter ved hjelp av enzymatisk hydrolyse. En ny, kontinuerlig metode har blitt foreslått ... -
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 a transcritical CO2 air/water reversible heat pump: analysis of domestic hot water production
(Chapter, 2020)As a natural refrigerant, carbon dioxide is safe, economic and environmentally sustainable and can be successfully utilized in heat pump and refrigeration systems operating according to transcritical cycles. This paper ... -
Experimental and numerical investigation of bubble migration in shear flow: Deformability-driven chaining and repulsion
(Journal article, 2023)We study the interaction-induced migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organize into chains aligned in the flow direction, similarly to particles in viscoelastic ... -
Experimental and Numerical Investigation of Coupled Vessel and Moonpool Responses
(Master thesis, 2020)Denne oppgaven tar for seg den gjensidige koblingen mellom moonpoolrespons og skipsbevegelser, ved gjennomføring av eksperiment og numeriske simuleringer. Et parameterstudie på forholdet mellom moonpoolbredde og skipsbredde ... -
Experimental and numerical investigation of filled thermoset polymers as mechanical interface in fine tolerance applications
(Master thesis, 2015)As a part of reducing costly processes in production of marine thrusters, casting and machining of large steel parts is proposed to be replaced by welding of smaller elements. This does however require a procedure for ... -
Experimental and Numerical Investigation of Floating Solar Islands
(Master thesis, 2017)In this master thesis, the dynamical behavior of a floating solar island in waves and current has been investigated. The solar island consists of a torus were the inner part is covered with a membrane. Underneath the ... -
Experimental and numerical investigation of nonlinear diffraction wave loads on a semi-submersible wind turbine
(Peer reviewed; Journal article, 2021)In a severe sea state, nonlinear wave loads can excite resonant responses of floating wind turbines either at high (structural) or low (rigid body motions) natural frequencies. In the present work, a computational fluid ... -
Experimental and numerical investigation of oil-water dispersions - Eksperimentell og numerisk analyse av olje-vann dispersjoner
(Master thesis, 2016)Crude oil in the reservoir is accompanied by formation water. Separating water from oil offshore before transporting it is necessary. This requires compact and robust separators. In order to optimize the design of separators, ... -
Experimental and numerical investigation of oil-water separation
(Master thesis, 2014)Separation of oil-water mixtures is essential to prepare the productsprior to transportation. This is, among others things, due to salesspecifications, minimisation of corrosion, and reduction of transporta-tion costs. The ... -
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 residual stresses in proximity girth welds
(Peer reviewed; Journal article, 2023)International fabrication codes and standards provide minimum distance criteria for proximity welds, although rigorous justification is lacking. These distances are either based on practical experience or mutual agreement ... -
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 Investigation of Speed Loss due to Seakeeping and Maneuvering
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:193, Doctoral thesis, 2013)Accurate prediction of the real voyaging speed for ocean‐going vessels in the actual weather condition is important for the expanding shipping industry. Ship owners are always aiming at achieving the highest profit, so ... -
