Investigation of U-tube effect in drilling operation
(Master thesis, 2010)The U-tube effect is present when drilling with a low riser return system(LRRS)or a dual gradient system(DGS). For the LRRS the U-tube effect will initiate asthe surface mud pump is shut down. The mud level in the drill ... -
Investigation of unsteady flow in the vaneless gap between impeller and diffusor.
(Master thesis, 2016)I denne oppgaven er det undersøkt hvorvidt vibrasjoner i en vertikalsentrifugalpumpe stammer fra sekundærstrømninger i gapet mellom impellerog diffusor. En model av dette gapet ble laget ut fra arbeidstegninger overpumpen ... -
An investigation of using CO<inf>2</inf> heat pumps to charge PCM storage tank for domestic use
(Journal article; Peer reviewed, 2023)Current investigations mainly focused on onefold phase change material (PCM) storage tank charging process, while the integration between a heat-source device and a PCM storage tank has been seldom considered. The investigation ... -
Investigation of Vision Transformers for Visual Place Recognition
(Master thesis, 2021)Fremskritt innen autonom robotikk kan ha store konsekvenser for samfunnet som helhet i fremtiden. Et av de største hindrene som forhindrer virkelig autonome roboter er utfordringen med å skulle kunne sikkert lokalisere seg ... -
Investigation of WAG Potential using Compositional Model
(Master thesis, 2016)Water-alternating-gas (WAG) injection is a commonly used enhanced oil recovery (EOR) technique, for which the aim is to increase vertical sweep efficiency and reduce mobility of injected fluids by injecting water and gas ... -
Investigation of Water Injection Performance and Potential on Eldfisk - A Simulation Study
(Master thesis, 2014)Investigation of water injection performance and potential on Eldfisk, with the use of reservoir simulation. -
Investigation of wave transformation and breaking processes in the coastal zone using REEF3D
(Master thesis, 2018)Several human activities and industries that contribute in shaping the communities and economies around the world are located in the coastal zone. Therefore, it is very crucial to understand the behaviour of the coastal ... -
Investigation of wave-induced nonlinear load effects in open ships considering hull girder vibrations in bending and torsion
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:357, Doctoral thesis, 2012)For ships with open cross sections, such as container vessels, it is of primary importance to accurately estimate torsional moment (TM) and horizontal bending moment (HBM) as well as vertical load effects. In recent decades, ... -
Investigation of Wave-Induced ULS and ALS Characteristic Loads and Responses on a Pile Structure in the Ekofisk Area - Importance of Breaking Waves
(Master thesis, 2016)A set of metocean contour lines corresponding to annual exceedance probabilities of 10^(-2) and 10^(-4) describing the environmental conditions at the Ekofisk area are established based on hindcast data. These are divided ... -
investigation of which sea states yield the dominating contribution to fatigue accumulation in offshore structure
(Master thesis, 2015)In assessment of the fatigue damage, it has been assumed that the moderate sea states (significant wave height ranged between 4-8m) should have major influence on the offshore structures because they have relatively more ... -
Investigation on an Open Cycle Water Chiller based on Desiccant Dehumidification
(Master thesis, 2012)In this thesis, a novel open cycle desiccant dehumidification system is experimentally studied. The system is installed and operated at Shanghai Jiao Tong University (SJTU) as part of the Green Energy Laboratory (GEL) ... -
Investigation on Ash Slagging Characteristics during Combustion of Biomass Pellets and Effect of Additives
(Journal article; Peer reviewed, 2017)This study reports a systematic investigation into ash slagging behavior during combustion of barley straw and barley husk pellets with or without additives in a residential pellet burner. The slagging tendencies of the ... -
Investigation on CO2 Ground-coupled Heat Pumping System with Ejector
(Master thesis, 2015)After the proposal of CO2 transcritical cycle in 1980s by Professor Gustav Lorentz, researchers have looked into theoretical and experimental research, as well as commercial system development to improve transcritical ... -
Investigation on Different Shapes of Broad-crested Weirs by Means of CFD
(Master thesis, 2019)Weirs are a type of hydraulic structure used for flow measurement, to regulate the water level in hydropower plants, and for the diversion of water to a reservoir. In this study, the flow over various shapes of broad-crested ... -
Investigation on Flooding-Resistant Performance of Integral Abutment and Jointless Bridge
(Peer reviewed; Journal article, 2020)Bridge washouts connected to flood events are deemed one of the main reasons for structural collapse. Compared to traditional continuous jointed bridges, integral abutment and jointless bridges (IAJBs) have better lateral ... -
Investigation on heat recovery strategies from low temperature food processing plants: Energy analysis and system comparison
(Chapter, 2021)Industrial food processing plants often have significant thermal requirements at both low and high temperatures. These plants can produce a variety of products including frozen, chilled and grilled/steamed foodstuff, ... -
Investigation on methods for making detailed digital models of sculptures and other artefacts
