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 to predict mass transfer in pulsed sieve plate extraction columns
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)A 2D CFD-PBM based numerical model to predict interphase mass transfer in a Pulsed Sieve Plate Column (PSPC) is reported. The model is based on Euler-Euler interpenetrating continuum approach. Drag law due to Schiller and ... -
CFD Simulation Delivered as SaaS for Building and HVAC Design Testing
