Investigation and Improvement of Vertical Axis Wind Turbine Prototype Manufactured by "Wind El Norway As"
(Master thesis, 2022)Energietterspørselen øker med tiden, så nye bærekraftige og fornybare metoder må brukes for å dekke etterspørselen, og reduserer dermed utslippene av fareelementer fra gamle drivstoffbaserte teknologier. Fornybare ... -
Investigation and modelling of plastic deformation aided by in situ monitoring techniques
(Doctoral theses at NTNU;2022:347, Doctoral thesis, 2022)A synergy from three modern in situ techniques - infrared thermography, digital image correlation, and acoustic emission - used concurrently has been obtained to gain deeper insight into deformation kinetics and energy ... -
Investigation and validation of a Francis turbine at runaway operating conditions
(Journal article; Peer reviewed, 2016)Hydraulic turbines exhibit total load rejection during operation because of high fluctuations in the grid parameters. The generator reaches no-load instantly. Consequently, the turbine runner accelerates to high speed, ... -
Investigation fatigue crack initiation and propagation cruciform welded joints by extended finite element method (XFEM) and implementation SED approach
(Peer reviewed; Journal article, 2022)This study has used the strain energy density (SED) approach to evaluate the stress intensity factor (SIF) of cracked cruciform welded joints in Hardox 450 steel. A microstructural analysis was made of Hardox 450 steel ... -
Investigation in ICT Contributions to Collaborative Maturity in OEM Projects
(Master thesis, 2016)Shipbuilding projects take place in an original equipment manufacturer (OEM) project environment that produces a low volume of highly customizable products in a global supply chain. This network must collaborate efficiently ... -
Investigation in scale effects on propellers with different magnitude of skew by CFD methods
(Master thesis, 2015)Scale effects on the open-water performance of marine propellers are the problems to be investigated to the researchers and ship designers. Present thesis analyse the scale effects of marine propellers by CFD methods. ... -
Investigation into Structure and Behaviour of Laminar and Turbulent Flames by Planar Laser-Induced Fluorescence Measurements

An Investigation into Technological Potentials of Library Intralogistics Operations
(Chapter, 2023)The efficiency of operations in service-oriented organizations is amongst the primary objectives. Libraries are no exception in this context, and this goal becomes even more complex due to being a non-profitable entity. ... -
Investigation into the Capabilities of Linear Theory for Numerical Modelling of Wave-Body Interactions for a 2D Heaving Buoy - Application to Wave Energy Converters
(Master thesis, 2017)Numerical modelling of wave energy converters (WECs) is currently an area of interest within the marine renewable energy industry, due to its ability to streamline design processes and accelerate scientific understanding. ... -
Investigation into the effect of simulating a 3D cylindrical fluidized bed reactor on a 2D plane
(Journal article; Peer reviewed, 2013)2D planar simulations of 3D cylindrical fluidized bed reactors are routinely carried out in order to reduce computational costs. The error involved in this simplification is largely unknown, however, and this study was ... -
Investigation of a Coarse Silt Deposit by Varied Rate CPTU Testing
(Doctoral theses at NTNU;2021:320, Doctoral thesis, 2021)Well-explored methods for the interpretation of CPTU and laboratory tests for clay and sand materials exist, assuming undrained and drained conditions, respectively. The determination of design parameters in silt is not ... -
Investigation of a Francis turbine during speed variation: Inception of cavitation
(Peer reviewed; Journal article, 2020)Variable-speed operation of a hydro turbine is considered as an alternative option to meet fluctuating energy demand as it allows high-ramping rate. Cavitation can be a limiting factor to utilize the variable-speed technology ... -
