Comprehensive Char Particle Gasification Model Adequate for Entrained-Flow and Fluidized-Bed Gasifiers
(Journal article; Peer reviewed, 2017)A robust, single-particle gasification model is presented that is capable of predicting char particle behavior in environments established in typical fluidized bed and entrained flow gasifiers. It employs a heterogeneous ... -
Well integrity for CO2 injection from ships: Simulation of the effect of flow and material parameters on thermal stresses
(Journal article; Peer reviewed, 2017)Ships have been shown to be the most cost-effective way to transport CO2 from many sources in the Nordic region to offshore storage sites. Injection from ships introduces new challenges for the integrity of CO2 injection ... -
Development of a scale model of a Modular Multilevel Converters
(Peer reviewed; Journal article, 2017)Modular Multilevel Converters are now being introduced in the power grid. Control systems for these converters are complex with many degrees of freedom. Simulation models are useful for exploring control algorithms, but ... -
Possibilities for energy recovery by steam compression cycles
(HighEFF-rapport;D3.2_2017.05, Research report, 2017)A significant amount of the industrial energy consumption is related to process heat. Several industries use heat in ranges reachable by heat pumps, and temperatures from 100-200℃ are especially needed in the paper and the ... -

Experiences With cable faults located at metallic screen connections
(CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)Overheating of metallic ground screen connections at accessories of single core cables are the root cause of severe insulation failures in the distribution network. The overheating is due to a high transition resistance ... -
A Comparative Study of Methods for Estimating Virtual Flux at the Point of Common Coupling in Grid-Connected Voltage Source Converters with LCL Filter
(Journal article; Peer reviewed, 2017)Grid synchronization based on virtual flux (VF) estimation allows for control of grid-connected power converter without depending on ac-voltage measurements. This is useful in voltage-sensor-less applications for reducing ... -
Prediction of the water/oil interfacial tension from molecular simulations using the coarse-grained SAFT-γ Mie force field
(Journal article; Peer reviewed, 2017)This work is framed within the Ninth Industrial Fluid Properties Simulation Challenge, with the aim of assessing the capability of molecular simulation methods and force fields to accurately predict the interfacial tension ... -
European power market analyses to be carried out within FME ZEN : ZEN deliverable D5.3.1 for 2017
(SINTEF Rapport;2017:00082, Research report, 2017)Local energy solutions such as the utilization of local renewable energy resources, and increased energy efficiency, are important for being able to reduce European greenhouse gas emissions to amounts that are in line e.g. ... -

Modelling of non-uniform lines using rational approximation and mode revealing transformation
(Journal article; Peer reviewed, 2017)The authors present a methodology to improve the rational modelling of non-uniform lines (NuLs). First, they formulate a segmented chain matrix representation of the NuL, which is converted into a nodal admittance formulation ... -
Grid Integration of offshore wind farms using a Hybrid HVDC composed by an MMC with an LCC-based transmission system
(Peer reviewed; Journal article, 2017)This paper presents a hybrid HVDC-transmission system composed by a Full-Bridge Modular Multilevel Converter (FB-MMC) and a Line-commutated Converter (LCC) from the grid integration of offshore wind farms. The operational ... -
Field dependent conductivity of n-pentane
(Proceedings of IEEE International Conference on Dielectric Liquids;2017, Chapter; Peer reviewed, 2017)A sensitive differential charge measurement technique was used to measure the conduction current from a sharp needle in a needle plane geometry in n-pentane. The current was measured at voltages up to the threshold for ... -
