A CFD STUDY ON THE IMPACT OF BARRIERS AND NONUNIFORMITIES ON FURNACE TAPPING
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Tapping of slag and metal from metal producing furnaces are often inconsistent and it is difficult to predict the outcome of the process. Nonuniformities in the particle bed has been hypothesized as reasons for inconsistent ... -
TO QUANTIFY MIXING QUALITY IN A SINGLE SCREW EXTRUDER SIMULATION
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Polymer mixing with a single screw extruder is a common process in industry. The mixing quality depends (amongst others) on the screw geometry. The main objective of this study was to develop a method for quantifying ... -
COMPREHENSIVE MODEL FOR BLAST FURNACE USING OPENFOAM®
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Blast furnace is a complex, multi-phase and high temperature reactor involving multiple reactions between phases, heat transfer and phase change. Limited options are available to know internal state of the furnace through ... -
Numerical simulation of bubble transport and splitting dynamics for varying bifurcation angle
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Gas embolotherapy is a recent potential cancer treatment. The technique is based on starving the tumors by cutting off the blood supply using perfluorocarbon (PFC) bubbles. The volatile PFC droplets are injected in the ... -
VOLUME-OF-FLUID SIMULATION OF GAS DISSOLUTION IN LIQUID: RISING BUBBLES AND CO2 TRAPPING
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Multiphase multispecies transport is an essential field of study for a wide range of applications including bubble reactors and CO2 storage in the subsurface. Modelling of these processes is challenging due to the ... -
DIRECT NUMERICAL SIMULATION STUDY ON THE FREE LIQUID AREA IN LIQUID-PARTICLE AGGLOMERATES.
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Multiphase flows often occur in intensified industrial processes and understanding these complex processes is instrumental in their design and optimisation. In gas-phase polymerisation reactors, the heat management is ... -
TOWARD COMPUTATIONAL MODELS OF ARC DYNAMICS IN SILICON SMELTERS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)The production of silicon in electric smelting furnaces is a complex and energy-intensive process. High current plasma arcs are used in such furnaces to generate the temperatures required for the chemical reaction of ... -
IMPROVEMENT OF EULER-EULER SIMULATION OF TWO-PHASE FLOW BY PARTICLE-CENTER-AVERAGED METHOD
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)The standard Euler-Euler modelling is based on the phase-averaged method and the forces of the bubble are the function of gas volume fraction. However, the closure models for the forces are developed based on the measured ... -
DIRECT NUMERICAL SIMULATION OF MASS TRANSFER FROM A SINGLE BUBBLE VIA AN IMPROVED SUBGRID SCALE MODEL
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Hydrogenation, oxidation and alkylation are just some of the processes which are performed in bubble columns. One of the reasons to use a bubble column for these processes is the high interfacial mass transfer coefficients. ... -
MODELLING OF MASS TRANSFER IN A STEELMAKING LADLE
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Mass transfer between liquid steel and slag is an important point during secondary metallurgy for prediction of the chemical reaction rate and adjustment of liquid steel composition. We want to study this phenomenon in ... -
MODELING A TWO-PHASE FLOW IN A DEVICE TO REDUCE THE MUSCLE TONE OF THE HANDS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)In this work, a new design of internal channels for a pneumatic mechanical device was proposed to reduce the muscle tone of the hands. The new design uses a two-phase gas-liquid system as a working medium. Numerical ... -
INVERSE MODELLING OF INTERFACIAL TENSION BETWEEN FERROALLOY AND SLAG USING OPENFOAM
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)The entrainment of molten ferroalloy droplets in slag during tapping operations is strongly related to turbulence and interfacial forces between alloy and slag. Therefore, interfacial phenomena are of great importance ... -
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 ... -
COMBINING AN IMPLICIT SOLUTION WITH AN EXPLICIT CORRECTOR STEP FOR THE SOLUTION OF THE CONTINUITY EQUATIONS IN A TWO-FLUID SOLVER
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)To model two-phase flows in industrial applications, for example the raceway zone in a blast furnace, an Eulerian two-fluid model is usually the method of choice. It has proven to predict the behavior of gas-solid flows ... -
ON MODELLING ELECTROCHEMICAL GAS EVOLUTION USING THE VOLUME OF FLUID METHOD
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)In this work we describe the various building block relevant in simulating electrochemical gas evolution using Volume of Fluid (VOF) method. These building blocks are implemented in the VOF solver available in OpenFOAM® ... -
