A linear State-Space Model of an Offshore Wind Turbine, Implemented in the STAS Wind Power Plant Analysis Program
(SINTEF Energi. Rapport;TR A7474, Research report, 2015)A set of MATlab/Octave scripts have been developed, which output state matrices describing the linearized aerolastic dynamics of an offshore wind turbine. The aerodynamic model is based on momentum balance,and includes ... -
A method for simulating two-phase pipe flow with real equations of state
(Journal article; Peer reviewed, 2014)Common two-fluid models for pipe flow assume local non-equilibrium regarding phase transfer. To solve the two-fluid models together with accurate equations of state for real fluids will in most cases require mechanical, ... -
A mobile application for on-site risk based decision support
(CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)Maintenance and renewal decisions are essential parts of distribution system asset management as means to control cost, performance and risk. This paper reports on the development of a mobile application used for in-the-field ... -

A modified homogeneous relaxation model for CO2 two-phase flow in vapour ejector
(Journal article; Peer reviewed, 2016)In this study, the homogenous relaxation model (HRM) for CO2 flow in a two-phase ejector was modified in order to increase the accuracy of the numerical simulations The two- phase flow model was implemented on the effective ... -
A new approach to the identification of high-potential materials for cost-efficient membrane-based post-combustion CO2 capture
(Journal article; Peer reviewed, 2018)Developing “good” membrane modules and materials is a key step towards reducing the cost of membrane-based CO2 capture. While this is traditionally being done through incremental development of existing and new materials, ... -

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 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 ...
