Simulation and modeling of ultrasonic pitch-catch through-tubing logging
(Journal article, 2016)Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the sealing material and to determine the structural integrity status. Although ultrasonic pitch-catch logging in single-casing ... -
Simulation and parametric study of a building integrated transpired solar collector heat pump system for a multifamily building cluster in Sweden
(SINTEF Proceedings;5, Chapter; Peer reviewed, 2020)Solar integrated building envelopes represent a significant energy harvesting potential in an era of decentralized building energy systems. This paper aims to simulate an energy system that consists of a transpired air ... -
A simulation concept for generic simulation of multi-material flow using staggered cartesian grids
(SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)Simulation of multiphase flows is generally treated by various classes of Eulerian methods, Lagrangian methods, and various combinations of these. In the SIMCOFLOW initiative, we have set out to develop a framework for ... -
Simulation model for the propagation of second mode streamers in dielectric liquids using the Townsend-Meek criterion

A simulation model to assess emission reduction policies in tourism transport: Case study of the Geiranger fjord UNESCO world heritage site in Norway
(Peer reviewed; Journal article, 2022)Tourism transport may lead to significant air emissions and congestion problems on road networks. This is particularly troublesome for nature-based tourism destinations, as they often are in rural areas with low transportation ... -
Simulation of airflow past a 2D NACA0015 airfoil using an isogeometric incompressible Navier-Stokes solver with the Spalart-Allmaras turbulence model
(Journal article; Peer reviewed, 2015)The work presented in this paper concerns the efforts of conducting a computational fluid dynamics (CFD) simulation of air flow past a fixed 2D NACA0015 airfoil at high Reynolds number (Re=2.5×106Re=2.5×106) using an ... -
Simulation of Anti-reflection Coated Carbonaceous Spectrally Selective Absorbers

Simulation of brash ice behaviour in the Gulf of Bothnia using Smoothed Particle 1 Hydrodynamics formulation
(Peer reviewed; Journal article, 2021)The repeated passage of ships through ice-infested waters create a field of broken ice pieces. The typical size of the broken ice pieces is generally <2.0 m. This area might be referred to as a brash ice field. The movement ... -
Simulation of chemical looping combustion process in a double looping fluidized bed reactor with cu‐based oxygen carriers
(SINTEF Proceedings;2, Chapter, 2017)Chemical looping combustion (CLC) is an attractive technology that produces a pure CO2 stream and therefore the CO2 can be readily recovered by condensing water vapour. In order to understand the physical phenomena and to ... -
Simulation of Condensation in Biogas containing Ammonia
(Peer reviewed; Journal article, 2021)Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ... -
Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS
(Journal article; Peer reviewed, 2018)Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ... -
Simulation of dew points in raw biogas using PR and SRK equations of state :
(Peer reviewed; Journal article, 2019)Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ... -
Simulation of dispersion of immiscible fluids in a turbulent couette flow
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Dispersion of immiscible fluids in a Couette device, in which the inner cylinder rotates whereas the outer one is immobile, is modelled. Two different modelling approaches are employed. The 1st approach is based on solving ... -
Simulation of DSL systems
(Research report, 2007)This report contains simulations of performance for different versions of ADSL, VDSL and SHDSL in 0.4 mm twisted pair cables. An important part of the work has been to investigate the compatibility between different DSL ... -
Simulation of ductile-to-brittle transition combining complete Gurson model and CZM with application to hydrogen embrittlement
(Peer reviewed; Journal article, 2022)A general simulation framework for modelling ductile-to-brittle transition in metals is proposed. The method combines the complete Gurson model and cohesive zone model, which brings ductile and brittle fracture mechanisms ... -
SIMULATION OF ENTRAINMENT OF DROPLETS IN NON-RESOLVED WIND-WAVE FLOWS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)In this study we focus on a generic method to model the generation of droplets from a non-resolved simulation of free surface flow. The application is entrainment of droplets from the large-scale interface of waves ... -
Simulation of fluid flow through real microannuli geometries
(Peer reviewed; Journal article, 2020)Debonding of well cement towards casing or rock, i.e. microannuli formation, is a typical failure mode of cement barriers. Consequently, such microannuli may act as leak paths during leakages of downhole fluids such as ... -
Simulation of gas-liquid flows in separators. A Lagrangian approach
(Chapter; Peer reviewed, 2017)In order to simulate the separation efficiency of gas scrubbers, we have formulated and implemented a version of the Single-Particle Method. The method is suitable for CFD simulations of gas-droplet flows, and is based on ... -
