MODELLING OF WAX DEPOSITION IN OIL PIPES: A DISPERSED MULTIPHASE TURBULENT FLOW APPROACH
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Crude oils are complex mixtures of hydrocarbons including high molecular weight paraflin waxes. When a "waxy" crude oil flows through a cold pipeline whose temperature is below the wax appearance temperature, e.g. in ... -
Modelling thermal effects in the molten iron bath of the HIsmelt reduction vessel
(SINTEF Proceedings;1, Chapter, 2015)Over a thirty year period the HIsmelt process has been developed as an alternative to the traditional blast furnace for the production of pig iron. This process involves the injection of fine iron ore and non-coking coal ... -
Modified Dolomite-Based Pellets for High Temperature Post-Combustion Co2 Capture
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)In this study, synthetic dolomite-based pellets were prepared by means of one-pot method. Zr and Ce were used as modifier and aluminate cement was employed as binder. The addition of the promoters by two different routes ... -
Moisture-dependent insects (silverfish species and psocid species (Psocoptera)) in modern buildings – a sign of hidden moisture and mould damages
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Through the last 10 years, it has been an increasing occurrence and activity of moisture-dependent insects in modern buildings. Grey silverfish (Ctenolepisma longicaudata) is the most common species, but it is also an ... -
Molecular to Process Scale: A Review of Holistic Direct Air Capture Contactor Design
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Air-sorbent contactors are an essential part of direct air capture processes. Their design can have a great influence on the process energy demand and efficiency. Three aspects of this design have been identified and ... -
Monitoring Mold growth and VOC Emissions from Wood Wool Insulations under Unfavorable Hygrothermal Conditions
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Mold growth on indoor surfaces can lead to severe human health effects. The presence of bio-based surfaces under high humidity conditions is expected to favor its development. This study used a custom-built wall at a 1:1 ... -
Monitoring of Co2 Well Plug Integrity. Electrical Response of Cement/CNF Sensor to Mechanical Load, Water Saturation and Carbonation
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)CO2 storage wells will eventually need to be permanently plugged and abandoned. Subsidence, fault/fracture reactivation or chemical degradation can all adversely affect well plug integrity leading to CO2 leakages. Thus, ... -
Mucociliary clearance is humidity dependent–contrary to common belief
(SINTEF Proceedings;9, Chapter, 2021)Efficient mucociliary clearance (MCC) is a precondition for the moistening capacity of human noses. A review of the literature reveals that only young and healthy individuals can maintain efficient nasal MCC in low ambient ... -

Multi-scale process models to enable the embedding of CFD derived functions: Curtain drag in flighted rotary dryers
(SINTEF Proceedings;1, Chapter, 2015)Flighted rotary dryers are large industrial devices which are commonly used to dry mineral ores and mineral concentrates, as well as other valuable commodity products. They are high capital cost units as well as large ... -
Multiphase Direct Numerical Simulations (DNS) of Oil-Water Flows Through Homogeneous Porous Rocks
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Water flooding is commonly used to recover oil from porous rocks using pressurized water. Present study focuses on fully resolved pore-scale level multiphase Direct Numerical Simulations (DNS) of oil-water flows through ... -
Multiphase flow modelling of furnace tapholes
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Pyrometallurgical furnaces of many varieties make use of tapholes in order to facilitate the removal of molten process material from inside the vessel. Correct understanding and operation of the taphole is essential for ... -
A Multiscale Approach for Evaluating UTSA-16 Adsorbent for Post Combustion Carbon Capture
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)UTSA-16 is considered as one of most promising Metal-Organic Frameworks (MOFs) for post combustion carbon capture in a vacuum swing adsorption (VSA) process. Current studies base their predictions on the equilibrium ... -
Multiscale approach to fully resolved boundary layers using adaptive grids
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Bubbly flows are omnipresent in most industrial processes. Often the intended use of such processes is to facilitate efficient mass and heat transfer for reactive flows. Mass and heat transfer coupled with fluid flow in ... -
