On pragmatism in industrial modeling
(SINTEF Proceedings;1, Chapter; Journal article, 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 ... -
Progress in Applied CFD : Selected papers from 10th International Conference on Computational Fluid Dynamics in the Oil & Gas, Metallurgical and Process Industries
(SINTEF Proceedings;1, Book; Conference object; Peer reviewed, 2015) -
Pragmatic CFD modelling approaches to complex multiphase processes
(SINTEF Proceedings;1, Chapter; Conference object, 2015)Modelling of complex multiphase processes in the minerals and energy resources industries requires a balance between the pursuit for detail and recognition of computational resource limitations, if it is to lead to effective ... -
CFD modeling of oil-water separation efficiency in three-phase separators
(SINTEF Proceedings;1, Chapter; Conference object, 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 gas entrainment at a propagating slug front
(SINTEF Proceedings;1, Chapter; Conference object, 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 ... -
Multi-scale process models to enable the embedding of CFD derived functions: Curtain drag in flighted rotary dryers
(SINTEF Proceedings;1, Chapter; Conference object, 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 ... -
A Baseline model for monodisperse bubbly flows
(SINTEF Proceedings;1, Chapter; Conference object, 2015)For practical applications the Euler-Euler two-fluid model relies on suitable closure relations describing interfacial exchange processes. The quest for models with a broad range of applicability allowing predictive ... -
CFD simulations of flow in random packed beds of spheres and cylinders: analysis of the velocity field
(SINTEF Proceedings;1, Chapter; Conference object, 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 ... -
Drop breakup modelling in turbulent flows
(SINTEF Proceedings;1, Chapter; Conference object, 2015)This paper deals with drop and bubble break-up modelling in turbulent flows. We consider the case where the drop/bubble slip velocity is smaller than or of the order of the turbulent velocity scales, or when the drop/bubble ... -
State of the art in mapping schemes for dilute and dense Euler-Lagrange simulations
(SINTEF Proceedings;1, Chapter; Conference object, 2015)Euler-Lagrange (EL) simulations are an extremely important tool for academia and industry to better understand gas-particle flows. We present simulation results for various gas-particle flow configurations using a variety ... -
Prediction of mass transfer between liquid steel and slag at continuous casting mold
(SINTEF Proceedings;1, Chapter; Conference object, 2015)For the prediction of steel desulphurization and dephosphorization or the evolution of slag composition at continuous casting mould, mass transfer between two immiscible fluids in a turbulent situation should be calculated. ... -
Numerical model for flow in rocks composed of materials of different permeability
(SINTEF Proceedings;1, Chapter; Conference object, 2015)In the oil and gas industry permeability measurements on rock samples give an indication of the capacity to produce the output (oil/gas etc). Permeability of small samples can be derived from x-ray Computed Tomography (CT) ... -
Modelling of the Ferrosilicon furnace: effect of boundary conditions and burst
(SINTEF Proceedings;1, Chapter; Conference object, 2015)A by-product from the ferrosilicon process is process gas which escapes into the furnace hood were it reacts with air. The process gas mainly consists of CO with some SiO and moisture. Modeling the gas behavior inside the ... -
Lattice Boltzmann simulations applied to understanding the stability of multiphase interfaces
(SINTEF Proceedings;1, Chapter; Conference object, 2015)Multiphase flow occurs in a multitude of industrial and technological situations ranging from oil and minerals recovery to microfluidics and nanofluidics. In all these cases we are interested in modelling the flow of two ... -
Modelling of particle transport and bed-formation in pipelines
(SINTEF Proceedings;1, Chapter; Conference object, 2015)Particle transport and bed formation in gas and condensate pipelines could occur under various flow regimes, from dilute flows to high mass-loading conditions, to conditions where particle beds form in the pipeline. Proper ... -
