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
(SINTEF Proceedings;1, Chapter, 2015)Slug flow is encountered frequently during multiphase fluid transport in pipes. The gas entrainment process at a slug front significantly affects the hydrodynamic behaviour of slug flows. Due to the complexity of the flow ... -
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
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)This paper discusses the application of cloud-based simulation in the early stages of an HVAC and building design process. Its goal is to show the benefits of the technology through a thermal comfort case study. The ... -
CFD simulation of the droplet size distribution of liquid‐liquid emulsions in stirred tank reactors
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Predicting the drop size distribution (DSD) is essential in particulate flows such as emulsions as it affects mass transfer and heat transfer. In the current work we developed a novel numerical method to account for droplet ... -
CFD SIMULATIONS OF AN ADDITIONAL H2 COMBUSTOR FOR IMPROVING EFFICIENCY IN CHEMICAL LOOPING COMBUSTION POWER PLANTS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Chemical looping combustion (CLC) is a promising technology for hydrocarbon fuel combustion with integrated CO2 capture. The CLC process imposes almost no direct energy penalty for separating CO2, but a large indirect ... -
CFD simulations of flow in random packed beds of spheres and cylinders: analysis of the velocity field
(SINTEF Proceedings;1, Chapter, 2015)In this work, we aim to better understand the flow patterns in a random arrangement of particles that might affect local mass transfer and effective reactor performance. Using the DEM code Grains3D, spherical or cylindrical ... -
