Calculation of airflow rate with displacement ventilation in dynamic conditions
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)Design of displacement ventilation (DV) is usually based on a heat balance method when overheating is the primary indoor climate concern. Various models for calculating airflow rate have been developed for several decades. ... -
Can we measure buildings' affordance?
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The term affordance is used in this paper to denote the capacity of buildings to provide occupants the possibility to control the indoor-environmental conditions so as to meet their needs and requirements. This is typically ... -
Can we trust what humans report? – myths and realities
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Human information is crucial for efforts in the field of buildings, health and experiences. Despite this, there is strikingly little focus on how it is created and may be understood. Division between e.g. “subjective”/ ... -
Carbon Capture with Metal Oxides in Molten Salts: MgO, SrO and CaO AS Sorbents
(SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)Carbon Capture in Molten Salts (CCMS) is an absorption-based method of separating CO2 from a flue gas or industrial gas through a thermal swing technique, where the sorbent is dissolved or partially dissolved in molten ... -

(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)This work focused on enhancing the CO2 capture kinetics of magnesite-derived MgO via alkali nitrate and mineral CaCO3 promoters for its application in the Carbonate Looping technology at intermediate temperatures (≤400°C). ... -
CCS in the European Energy Transition to Climate Neutrality
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)The transition of the European energy system to reach climate neutrality by 2050 will require a development and deployment of technologies capable of decarbonizing the energy system in an unprecedented scale. Increased ... -
CCS Public Perception Learnings Applied to Brazil
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Carbon Capture and Storage (CCS) is considered a relevant technology to deal with climate change mitigation. However, the technology is not yet known to the various audiences, be it by the government and legislators, by ... -
CFD APPROACH TO SIMULATE TWO PHASE FLOW INLINE-SEPARATOR COUPLING IBM, LES, LAGRANGIAN TRACKING AND VOF METHODS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)x Inline fluid separation using a swirl element is a recent technology for oil/gas processing. Centrifugal forces up to 100 times the gravitational acceleration separate the phases, leaving the heavy phase close to the ... -
CFD based study of dense medium drum separation processes
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Dense Medium Drum (DMD) separation is applied particularly in the coal and recycling industries. Characteristic of the process is a separation based on density, driven by the buoyancy and gravitational forces acting on an ... -
CFD Erosion Modeling of Blind Tees
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)In subsea components such as Production Trees (XT) where the production flow path is machined out of steel blocks, the flow changes direction abruptly at blind tees or sharp elbows, causing increased erosion risks compared ... -
CFD modeling of a commercial‐size circle‐draft biomass gasifier
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)This work was focused on a commercial-size (2MWth.) circle-draft biomass gasifier. In this work a threedimensional transient CFD (computational fluid dynamics) model was established to simulate the circledraft biomass ... -
CFD modeling of dynamic emulsion stability
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Assuring transport and separation of oil and water crude emulsions is of significant importance to the oil and gas industries. The crude oil, due to its profuse chemical composition, has complex dispersion and emulsion ... -
CFD modeling of oil-water separation efficiency in three-phase separators
(SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)Variations in oil properties or water content influence the rate of crude oil-water separation. This presents a challenge for separator operations when conditions change as fields mature, and for the design of new internals ... -
CFD modelling of an accidental release of a methane and hydrogen sulfide mixture in an offshore platform
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Oil & Gas plants are complex systems involving dangerous substances, potential origin of severe accidental scenarios. Therefore, according to Directive 2013/30/EU, a Risk Assessment (RA) is mandatory. A fundamental step ... -
CFD modelling of gas entrainment at a propagating slug front
