CFD Modelling of Alumina Feeding
(Journal article, 2018)The dissolution and distribution of alumina in molten cryolite bath is a complex process, involving heat and mass transfer, phase transition and dynamics for a particle population with variable size and properties. Although ... -
CFD Study on Continuous Tapping of Silicon
(Peer reviewed; Journal article, 2022)Silicon is mostly produced in rotating submerged arc furnaces with continuous tapping of metal. The burden is often dense due to condensates. Thus, furnace gas does not escape easily to the top of the burden and some gas ... -
Changes in Material Properties of Silicone and PVC Tracheostomy Tubes – In-vitro Prediction of Medical Device Material Performance In-vivo
(Master thesis, 2022)Abstract will be available on 2023-06-09 -
Chapter 9 - Coatings and surfaces with hydrophobic and anti-icing properties
(Chapter, 2019)Icing on surfaces has always been a problem if water is present under freezing conditions. The ice can cause large damage to equipment and installations, and it is therefore of greatest interest to look into possibilities ... -
Characterisation and Plasticity in Extruded Al-Mg-Si Profiles engaging In-situ EBSD
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:154, Doctoral thesis, 2007)A comprehensive characterisation and study of plasticity in two extruded Al-Mg-Si profiles has been carried out. The primary objective of the experimental work has been directed towards obtaining an improved understanding ... -
Characterisation of a Real-World Søderberg Electrode
(Peer reviewed; Journal article, 2021)Very little research on Søderberg electrodes has been published in the journal peer reviewed public domain. The main aim of this work is to characterise a Søderberg electrode that was cut off approximately 0.5 m below the ... -
Characterisation of an aluminium matrix nanocomposite wire manufactured by screw extrusion
(Master thesis, 2019)Kontinuerleg skrueekstrusjon av metaller (Metal Continuous Scew Extrusion, MCSE) er ein nyutvikla, fast tilstands produksjonsmetode, som tilrettelegg for framstilling av metallegeringar og komposittar med nye eigenskapar. ... -
Characterisation of Feed and Produced Material in Screw Extrusion of Titanium
(Master thesis, 2016)A novel method of extrusion of materials with high viscosity is being developed at NTNU, the method is based on screw extrusion, which is more known in the plastic industry. The process, at the end of the development cycle ... -
CHARACTERISATION OF IRIDIUM OXIDE BY SCANNING PROBE, ELECTROCHEMICAL, AND PHOTOELECTROCHEMICAL METHODS

Characterisation of Iridium Oxides for Acidic Water Electrolysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:190, Doctoral thesis, 2011) -
Characteristic properties and recyclability of the aluminium fraction of MSWI bottom ash
(Peer reviewed; Journal article, 2021)The increasing use of aluminimum in packaging applications results in many different aluminium-based products ending up in consumer mixed-waste bins. This waste is typically incinerated, generating an aluminium-containing ... -
Characteristics of Calcium-Aluminate Slags and Pig Iron Produced from Smelting-Reduction of Low-Grade Bauxites
(Journal article; Peer reviewed, 2018)Low-grade bauxite ores are not favorable in the conventional Bayer process for alumina production, as they are producing more bauxite residue (red mud) and accompanying lower alumina yield than high-grade ores. In the ... -
Characteristics of particulate emissions from aluminium electrolysis cells
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:314, Doctoral thesis, 2013)Modern sampling and analysis techniques were applied to study the morphology and composition of pot exhaust particles from aluminium smelters. In this study the total spectrum of pot exhaust particles from prebake electrolysis ... -
Characteristics of TI6AL4V powders recycled from turnings via the HDH technique
(Journal article; Peer reviewed, 2018)The objective of this research is for Ti6Al4V alloy turnings, generated during the machining of implants, to produce powders for the fabrication of Ti base coating via the cold spray method. In order to decrease the cost ... -
