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 ... -
Simulation of large-strain behaviour of aluminium alloy under tensile loading using anisotropic plasticity models
(Peer reviewed; Journal article, 2015)Cylindrical smooth and notched AA6060 samples were tested in tension. The material was either cast and homogenised or extruded with strong cube texture. The textured specimens demonstrated unusual shapes of the fracture ... -
Simulation of Low Frequency Motions in Severe Seastates Accounting for Wave-Current Interaction Effects
(ASME Proceedings | Offshore Technology;OMAE2017-62550, Chapter, 2017-06-25)Today’s industry practice assumes wave drift forces on floating structures can be computed from zero current wave drift force coefficients for the stationary floater, while simplified correction models introduce current ... -
Simulation of multi-market trading : a case study
(SINTEF Rapport;2019:01000, Research report, 2019)This report describes a study of day-ahead (DA) and intraday (ID) trade for a hydropower producer with a single reservoir and power plant. The study simulates the trade decisions and plant operation in a rolling-horizon ... -
Simulation of stress hysteresis effect on permeability increase risk along a fault
(Journal article; Peer reviewed, 2019)CO2 sequestration projects will in the coming years include both aquifer and depleted oil and gas field sites, with different stress paths and history. Stress changes and stress concentration effects on faults will have ... -
Simulation of two-phase viscous oil flow
(SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)Multiphase flows of heavy oils and other fluids with high apparent viscosity is a particular industrial challenge. Main challenges here is that interfacial waves, atomization at the large scale gas–liquid interface as well ... -
