A novel bench size model coalescer: Dehydration efficiency of AC fields on water-in-crude-oil emulsions
(Journal article; Peer reviewed, 2016)We describe herein the design of a small AC electrostatic model coalescer for investigating coalescence efficiency of water in oil emulsions. The function of the model coalescer is tested on emulsions with different water ... -
A preliminary investigation of the potential of radar-based short-term precipitation forecasting in Central Norway : an Experiment on using Lagrangian persistence for nowcasting of two events
(SINTEF Energi. Rapport;, Research report, 2013) -
A review on recent technological advancements in muliti-ejector concept
(Science et technique du froid;2018-3, Chapter; Peer reviewed, 2018) -
A robust method for calculating interface curvature and normal vectors using an extracted local level set
(Journal article; Peer reviewed, 2014)The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g. merging drops, ... -
A steady and quasi-steady state analysis on the CO2 hybrid ground-coupled heat pumping system
(Journal article; Peer reviewed, 2017)This article contains the steady and quasi-steady state analysis on a CO2 hybrid ground-coupled heat pumping system for warm climates. The hybrid system uses a combination of ambient air and ground boreholes as a heat sink ... -
A stochastic model for contact surfaces at polymer interfaces subjected to an electrical field
(Journal article; Peer reviewed, 2018)Morphology of the contact area between solid insulation materials ultimately determines the short- and long-term electrical properties of the complete insulation system. The main purpose of this paper is to propose a ... -
A stochastic weather generator based on resampling historical ensemble weather forecasts and its application to hydrological simulation
(SINTEF Rapport;, Research report, 2017) -
A Study on Densification and CO2 Gasification of Biocarbon
(Journal article; Peer reviewed, 2018) -
A techno-economic case study of CO2 capture, transport and storage chain from a cement plant in Norway
(Journal article; Peer reviewed, 2016)This paper investigates various alternatives for the application of CCS at a cement plant which is one of the focus site for CCS deployment in Norway. A matrix consisting of nine CCS alternative chains is analysed in order ... -
A Two-Fluid Model for Vertical Flow Applied to CO2 Injection Wells
(Journal article; Peer reviewed, 2016)Flow of CO2 in wells is associated with substantial variations in thermophysical properties downhole, due to the coupled transient processes involved: complex flow patterns, density changes, phase transitions, and heat ... -
A Virtual synchronous machine implementation for distributed control of power transformers in SmartGrids
(Journal article; Peer reviewed, 2015)The ongoing evolution of the power system towards a “SmartGrid” implies a dominant role of powerelectronic converters, but poses strict requirements on their control strategies to preserve stability andcontrollability. In ... -
Absorption of water in silicon gel
(Chapter; Peer reviewed, 2014)Water is an important enemy of an electric insulation system. Water vapour can be absorbed by electrical insulation materials (liquids or solid) and migrate in between the materials to achieve the same relative humidity ... -
AC Breakdown Voltage of 50-Year-Old Service Aged Hydro Power Generator Stator Bars
(Peer reviewed; Journal article, 2022)Randomly selected generator bars from a 50-year-old Norwegian hydro power generator were examined in this work. Typical non-destructive tests, as partial discharge and dissipation factor measurements were initially performed ... -
AC Corrosion of Electrically Heated Pipelines
(ISOPE - International Offshore and Polar Engineering Conference. Proceedings;2017, Chapter; Peer reviewed, 2017) -
AC Corrosion Tests of Carbon Steel, AlZnIn Anodes and 25Cr Duplex for Subsea Applications
(Chapter; Peer reviewed, 2021)This paper presents results from AC corrosion tests on 25Cr duplex and cathodically protected carbon steel. The results show that the corrosion rate is independent of transfer current density (0-200 A/m2) and power frequency ... -

Accelerating Efficient Installation and Optimization of Battery Energy Storage System Operations Onboard Vessels
(Peer reviewed; Journal article, 2022)Emerging large battery energy storage systems (BESSs) are key enablers in the electrification of the shipping sector. With huge government investments in BESSs, there are large gaps between the government supported BESS ... -
Accounting for component condition and preventive retirement in power system reliability analyses
(Peer reviewed; Journal article, 2023)Deteriorated power system components have a higher probability of failure than new components. Still, reliability of supply analyses traditionally model all components of the same type with the same probability of failure, ... -
Accounting for uncertainties due to high-impact low-probability events in power system development
(Peer reviewed; Journal article, 2021)In the long-term development of the electric power system, system operators should consider the socio-economic balance between grid investment costs and security of supply, including the risk of power supply interruptions. ...
