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 ... -
Experimental and numerical investigation of strain distribution of notched lead fatigue test specimen
(Journal article; Peer reviewed, 2018)The work here presented focuses on the test methodology related to effect of stress concentrators in strain controlled structures. Cable sheathing as used in subsea power cables are investigated by cyclic fatigue testing, ... -
An Experimental and Numerical Investigation of the Blast Response of Pre-damaged Aluminium Plates
(Master thesis, 2017)The dynamic response of thin, perforated aluminium plates subjected to blast load has been studied both experimentally and numerically. The experiments have been conducted in a shock tube facility, where the blast intensity ... -
Experimental and numerical investigation on a ejector for CO2 vapor compression systems
(Chapter, 2018)The use of two-phase flashing ejectors to improve the COP and capacity of CO2 vapor compression systems has become a key research topic in recent years. Although many experimental investigations focused on both the ejector ... -
Experimental and numerical investigation on the deformation behaviors of large diameter steel tubes under concentrated lateral impact loads
(Peer reviewed; Journal article, 2023)Large diameter steel tubes are widely used in bottom fixed and floating offshore wind turbines. Offshore wind turbines (OWTs) operating in the oceans are exposed to the risk of collisions when ships pass and dock at turbines. ... -
Experimental and numerical investigation on two-phase flow instabilities
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:4, Doctoral thesis, 2013)Two-phase flow instabilities are experimentally and numerically studied within this thesis. In particular, the phenomena called Ledinegg instability, density wave oscillations and pressure drop oscillations are investigated. The ... -
EXPERIMENTAL AND NUMERICAL INVESTIGATIONS OF A LEAD ALLOY USED IN SUBSEA POWER CABLE
(Master thesis, 2018)Subsea Power Cable are used to carry electric power in marine environment, where are commonly installed on the seabed. The internal conductor is wrapped by electric insulation and several protective layers, among these a ... -
Experimental and numerical investigations of a small scale double-reflector concentrating solar system with latent heat storage
