An experimental and numerical study of a three-lobe pump for pumped hydro storage applications
(Peer reviewed; Journal article, 2023)Pumped hydro storage (PHS) plays an important role as a matured technology that accounts for the vast majority of global energy storage capacity, and its expansion is therefore desirable. The expansion of PHS in mid- and ... -
Experimental and numerical study of a two-body heaving wave energy converter with different power take-off models
(Journal article; Peer reviewed, 2021)Wave energy is one of the most difficult energies to be captured among marine renewables. With the technical progress, wave energy converters (WECs) are being tested in relatively deeper waters, which makes floating concepts ... -
Experimental and numerical study of an aquaculture net cage with floater in waves and current
(Journal article, 2015)The mooring loads on an aquaculture net cage in current and waves are investigated by dedicated model tests and numerical simulations. The main purpose is to investigate which physical effects are dominant for mooring ... -
An experimental and numerical study of bolt and nut assemblies under tension loading
(Master thesis, 2016)The purpose of this master thesis is to investigate how the nut position affects the failure mode of single tensile loaded bolts under quasi-static conditions. A ductile bolt fracture is preferable from an engineering ... -
Experimental and numerical study of carbon dioxide mass transfer and kinetics in amine solutions
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:98, Doctoral thesis, 2012)In CO2 absorption processes large mass and heat transfer driving forces occur in several places, such as the bottom of absorber, water wash section and desorber. Mass transfer is a science that describes the relative motion ... -
Experimental and numerical study of current effects on a plastic containment boom
(Master thesis, 2021)Denne masteroppgava er en numerisk og eksperimentell studie gjennomført for å studere de hydrodynamiske effektene på lenser for oppsamling av plast fra havet. To-dimensjonale laboratorietester ble gjennomført for å analysere ... -
Experimental and Numerical Study of Density-Driven Natural Convection Mechanism During Storage of CO2 in Brine Aquifers
(Doctoral thesis at NTNU;2015:170, Doctoral thesis, 2015)Storage of CO2 into geological formations is a reasonable technical choice for decreasing carbon dioxide emissions to the atmosphere. Brine aquifers are considered as one of the most favorable options for this purpose ... -
Experimental and numerical study of dilation in mineral filled PVC
(Doctoral theses at NTNU;2020:388, Doctoral thesis, 2020)This thesis addresses the link between applied load and dilation caused by void growth in mineral-filled PVC employing both experimental and numerical techniques. The influence of stress triaxiality and strain rate on the ... -
Experimental and Numerical Study of Fluid Displacement in Subsea Pipe Sections
(Master thesis, 2017)The objective of the thesis is to study displacement operations in offshore petroleum industry. Typically MEG or Methanol is circulated through parts of the subsea production systems to lower their hydrocarbon content. ... -
Experimental and Numerical Study of Hybrid Concrete Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:259, Doctoral thesis, 2013)The hybrid concrete structures investigated in this project are beams composed by layers of different types of concrete. Normal density concrete (NC) is used as top (and bottom) layer combined with a layer of fibre reinforced ... -
Experimental and numerical study of hydrodynamic responses of a combined wind and wave energy converter concept in survival modes
(Journal article; Peer reviewed, 2015)The Spar Torus Combination (STC) concept consists of a spar floating wind turbine and a torus-shaped heaving-body wave energy converter (WEC). Numerical simulations have shown a positive synergy between the WEC and the ... -
Experimental and numerical study of hydrodynamic responses of a twin-tube submerged floating tunnel considering vortex-induced vibration
(Doctoral theses at NTNU;2020:392, Doctoral thesis, 2020)A pontoon-supported submerged floating tunnel (SFT) is a reasonable means crossing a fjord with large depth and width. A relevant design of such a tunnel consists of two identical tubes in a tandem configuration and suspended ... -
Experimental and numerical study of mooring chain residual stresses and implications for fatigue life
(Peer reviewed; Journal article, 2020)Residual stresses in large mooring chains were measured for the first time in this study. Two measurement techniques were employed (neutron diffraction and hole drilling). Elastic-plastic finite element simulation of the ... -
Experimental and Numerical Study of Non-Linear Motions of Ocean Farm 2 at Inspection Draught
