Novel true triaxial apparatus applied to the study of sand mass production under anisotropic stress conditions.
(Rock Mechanics for Natural Resources and Infrastructure Development (ISRM);2019, Chapter; Peer reviewed, 2019)Using a novel true triaxial setup, sand production tests on hollow quasi-cylinder Castlegate sandstone specimens have been performed on irreducible water saturated specimens with oil flow under varying levels of axial and ... -
Numerical Modeling of Radial Fracturing of Cement Sheath Caused by Pressure Tests
(Chapter; Peer reviewed, 2019)To achieve an acceptable level of zonal isolation, well integrity should be guaranteed in hydrocarbon production and geological CO2 sequestration. Well pressure test can cause different types of failures in the well system ... -
On Common Research Needs for the Next Generation of Floating Support Structures
(Chapter; Peer reviewed, 2022)The world is facing several industrial and societal challenges, such as providing enough renewable energy and enough safe and healthy food as formulated in the United Nations sustainable development goals. Using floating ... -
On pragmatism in industrial modeling
(SINTEF Proceedings;1, Chapter, 2015)Many natural or industrial processes are of extreme complexity, and where the time- and length scales range from an atomistic level to years and kilometers. Often the processes or phenomena consist of multiple sub processes ... -
On pragmatism in industrial modeling. Part III: Application to operational drilling
(SINTEF Proceedings;2, Chapter, 2017)In this paper, we will apply the concepts of pragmatic industrial modelling to the development of a real time drilling support tool. We develop requirements to such a modelling tool, regarding both input and output, model ... -
ON THE SURFACING MECHANISM OF BUBBLE PLUMES FROM SUBSEA GAS RELEASE
(Chapter, 2017)A subsea release of gas poses a risk to humans and assets at the surface. Assessing this risk requires knowledge on how much gas reaches the surface and how it is distributed at the surface. This can be estimated by various ... -
Patient Specific Numerical Simulation of Flow in the Human Upper Airways for Assessing the Effect of Nasal Surgery
(SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative ... -
Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous ... -
Phase Transformations from Quartz to Cristobalite
(The Minerals, Metals & Materials Series;2367-1181, Chapter, 2018)Two quartz types used in the silicon and ferrosilicon industry were heated to temperatures of 1600 and 1700 °C. The parameters varied were the temperature and the holding time at maximum temperature. The amount of quartz, ... -
Porous Carbon Anodes for the Supply of Methane during Electrowinning of Aluminium
(Chapter; Peer reviewed, 2016)One of the major downsides of the current aluminium production process is the high amount of CO2 e mission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2 ... -
Pressure Dependency of the Membrane Structure Parameter and Implications in Pressure Retarded Osmosis (PRO)
(Chapter; Peer reviewed, 2018)Pressure retarded osmosis (PRO) can be used to exploit the mixing energy e.g. between river water and sea water. A PRO membrane must be highly permeable for water, whereas salt ions should be retained. Furthermore, the ... -
Pseudo slug flow in viscous oil systems – experiments and modelling with LedaFlow
(11th North American Conference on Multiphase Technology;2018, Chapter; Peer reviewed, 2018)An experimental two-phase flow campaign with a viscous oil (100 cP) was conducted in the Large Scale 8" loop at the SINTEF Multiphase Flow Laboratory. The loop consisted of three main test sections, with pipe inclinations ... -
Recycling of the Flue Gas from Aluminium Electrolysis Cells
(The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Recycling of the flue gas from aluminium reduction cells is a possible method for increasing the CO2 concentration, thereby enabling CO2 capture. The present paper represents a preliminary study concerning some of the ... -
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 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 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 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 ... -
Slag-metal interactions in the FeMn tapping process: Interfacial properties and wetting
(Chapter, 2019)FeMn-alloys are produced by transforming ore and carbon materials into FeMn and slag at high temperatures in a furnace. Entrainment of FeMn in slag during tapping reduces the yield. Entrainment and subsequent separation ... -
