Experimentation on Surge waves in Three Phase Pipe Flows
(Master thesis, 2020)Det er utført forsøk i flerfaselaboratoriet ved NTNU med enkeltbølger (“surge waves”) i olje-vann-luft strøm i rør. Studien er en oppfølging av et tidligere prosjektarbeid. Forsøkene ble utført ved så lave luftrater som ... -
Experiments and CFD simulation of an air-conditioned tractor cabin for thermal comfort of tractor operators in Pakistan
(Journal article; Peer reviewed, 2023)Tractors are manufactured without air-conditioned cabins in Pakistan. This leads to thermal discomfort for tractor operators working under direct solar exposure. Therefore, this study aimed to design and install an ... -
Experiments and Modelling for the Control of Riser Instabilities: Forsøk og simulering for regulering av ustabil strøm i stigerør
(Master thesis, 2010)Multiphase flowline-riser systems sometimes encounter fluctuations in flow rate, pressure and liquid hold-up characterized as severe slugging. Slugging is undesirable because the piping and downstream receiving facilities ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
(Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
Experiments and Numeric Simulation on Displacement and Flushing of Hydrocarbon Fluid in Subsea Systems
(Master thesis, 2016)With the increasing number of subsea developments in the oil and gas industry, there is a need for more, and reliable, information on how to conduct safe and well informed subsea operations. One of the hot topics today is ... -
Experiments and simulations of empty and sand-filled aluminum alloy panels subjected to ballistic impact
(Journal article; Peer reviewed, 2017)In this study, we use a discrete particle method in combination with finite element analysis to describe the interaction between structures and granular media during ballistic impact. By applying a discrete particle method ... -
Experiments in the wind turbine far wake for the evaluation of an analytical wake model
(Journal article; Peer reviewed, 2017)Nowadays, not only the size of single wind turbines but also the size of wind farms is increasing. Understanding the interaction between the turbines and especially the wakes formed behind them are getting more important ... -

Experiments on gas flow with wet pipe walls
(Master thesis, 2013)A new experimental setup, for investigation of a possible pressure drop reduction in gas transport pipelines through indruduction of a liquid film at the pipe walls, is presented. Two experimental series are performed, ... -
Experiments on Surfactant Stabilized Oil-Water Dispersed Flow
(Master thesis, 2012)This thesis is a study on the behaviour of surfactant stabilized oil-water dispersed flow in horizontal pipes. Water in oil dispersions is a common phenomenon in the oil industry, where oil and water often are produced and ... -
Experiments on the droplet field in multiphase pipe flow
(Doctoral thesis at NTNU;2015:71, Doctoral thesis, 2015)Gas-liquid flows are very common in industrial applications and many times involve three phases. Experiments are important as basis for development of 1D flow models used for design of multiphase transport systems. The ... -
Experiments with a latent heat storage for frying
(Master thesis, 2021)Formålet med dette prosjektet har vært å teste et varmelagringssystem kombinert med en stekeplate, som skal brukes til matlaging. Systemet skal varmes med overflødig energi, eller fornybare energikilder på steder uten ... -
Explaining decoupling in high income countries: A structural decomposition analysis of the change in energy footprint from 1970 to 2009
(Peer reviewed; Journal article, 2020)The decoupling of energy use from economic growth is an essential element in the transition to a sustainable future. However, little is known about the long-term drivers of decoupling, especially considering the possibility ... -
Explaining the formation of sedimentary structures under antidunes using a 2D width-averaged numerical model
(Peer reviewed; Journal article, 2022)A new numerical model for computing the formation of sedimentary structures in a fluvial environment is presented. The model has been used to explain the strata-forming processes under antidunes in detail, including water ... -
Explaining the historical energy use in dwelling stocks with a segmented dynamic model: Case study of Norway 1960-2015
(Journal article; Peer reviewed, 2016)A segmented dynamic dwelling stock model is proven useful for understanding the development and changes of ageing building stocks, which is highly relevant for renovation measures and estimates of energy use and emissions ... -
Explicit isogeometric collocation for the dynamics of three-dimensional beams undergoing finite motions
(Journal article; Peer reviewed, 2018)We initiate the study of three-dimensional shear-deformable geometrically exact beam dynamics through explicit isogeometric collocation methods. The formulation we propose is based on a natural combination of the chosen ... -
Explicit Structural Response-Based Methodology for Assessment of Operational Limits for Single Blade Installation for Offshore Wind Turbines
(LNCE;volume 23, Chapter, 2019)The growing requirements of large-sized offshore wind turbines require heavier components to be lifted to large heights using installation vessels. This imposes a substantial risk of impact to the lifted components especially ... -
