(Master thesis, 2018)The objectives of this thesis have been to develop a script for a multiscale method based on first order homogenisation, to investigate estimation of properties and behaviour of unidirectional (UD) fiber composites. To ... -
Multiscale modelling of packed bed chemical looping reforming
(Journal article; Peer reviewed, 2017)A comparison of reactive flows on two distinct scales is presented here (i) Particle resolved direct numerical simulation (PR-DNS), and (ii) 1D packed bed model. The PR-DNS geometry is meshed with polyhedral elements both ... -
Multiscale Modelling of the Calcium Naphthenate Precipitation Reaction in Petroleum Processing
(Doctoral thesis at NTNU;2016:53, Doctoral thesis, 2016)The formation of calcium naphthenate precipitates occurring in the petroleum industry is both an undesirable side reaction and can introduce costly shutdowns and cleaning processes. Although the reaction has been studied ... -
Multiscale modelling using molecular dynamics and interfacecapturing methods for two-phase flow simulation of droplets covered with surfactants or asphaltenes, and applications to electrocoalescence

Multiscale models for large molecular systems: from development to applications
(Doctoral theses at NTNU;2023:17, Doctoral thesis, 2023)The atomistic description of complex molecular systems, such as solutions and biological moieties, requires some sort of compromise between computational efforts and accuracy. Low-level models can treat thousands of atoms, ... -
Multiscale partial charge estimation on graphene for neutral, doped and charged flakes
(Journal article; Peer reviewed, 2018)The minimal-basis iterative stockholder (MBIS) and restrained electrostatic potential (RESP) methods were applied to examine the effects of edges and of nitrogen and boron dopants on the atomic partial charges of neutral ... -
Multiscale Simulation of Thermal Flow in Porous Media
(Master thesis, 2016)In this thesis we develop a multiscale method that solves non-isothermal flow in porous media. A sequential formulation is established that decouples corresponding equations into three systems, one pertaining pressure, one ... -
Multiscale thermo-hydraulic modeling of cryogenic heat exchangers
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:2, Doctoral thesis, 2012)The cryogenic industry has experienced a continuous growth in the last decades, partially sustained by the worldwide development of Liquefaction of Natural Gas (LNG) projects. LNG technology provides an economically feasible ... -
Multiscale Wavelet-Driven Graph Convolutional Network for Blade Icing Detection of Wind Turbines
(Peer reviewed; Journal article, 2022)Blade icing detection is critical to maintaining the health of wind turbines, especially in cold climates. Rapid and accurate icing detection allows proper control of wind turbines, including shutting down and clearing the ... -
Multiscale X-ray tomography for shale microstructure and mechanical behaviour
(Doctoral theses at NTNU;2024:39, Doctoral thesis, 2024)Studying shales and other sedimentary rock systems is important to provide a fundamental understanding of their microstructural properties, including the mechanical response and the permeability of liquids and gases. ... -
Multiscale-Streamline Inversion for High-Resolution Reservoir Models
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:211, Doctoral thesis, 2007)The topic of this thesis is streamline-based integration of dynamic data for porous media systems, particularly in petroleum reservoirs. In the petroleum industry the integration of dynamic data is usually referred to as ... -
Multisensor Fusion for Intrusion Detection and Situational Awareness
(Master thesis, 2017)Cybercrime damage costs the world several trillion dollars annually. And al-though technical solutions to protect organizations from hackers are being con-tinuously developed, criminals learn fast to circumvent ... -
Multisensory input modulates memory-guided spatial navigation in humans
(Peer reviewed; Journal article, 2023)Efficient navigation is supported by a cognitive map of space. The hippocampus plays a key role for this map by linking multimodal sensory information with spatial memory representations. However, in human navigation ... -
