The Effect of Impurities on γ-Alumina Chlorination in a Fluidized Bed Reactor: A CPFD Study
(Peer reviewed; Journal article, 2022)Alumina is one of the most widely used materials today, with a total annual production of millions of tonnes of highly pure alumina. A large portion of this is used to make metal aluminum. Apart from that, a growing amount ... -
Effect of Inclusion and Filtration on Grain Refinement Efficiency of Aluminum Alloy
(Peer reviewed; Journal article, 2022)It is well known that the filtration efficiency of ceramic foam filters (CFF) on aluminum melt can be significantly reduced by the addition of grain refiner particles under a high inclusion load. Also, it is usually ... -
Effect of laser structured micro patterns on the polyvinyl butyral/oxide/steel interface stability
(Peer reviewed; Journal article, 2020)This work investigated the effect of steel substrate topography and roughness on cathodic disbonding resistance and wet adhesion of the polyvinyl butyral/oxide/steel interface. Laser structuring was employed to pattern ... -
Effect of liquid viscosity on the performance of a non-porous membrane contactor for CO2 capture
(Journal article; Peer reviewed, 2019)The effect of liquid viscosity on the performance of a non-porous membrane contactor is important to study for a proper solvent selection and process design. In this work, the overall mass transfer coefficient for MEA- and ... -
Effect of long periods of corrosion on the fatigue lifetime of offshore mooring chain steel
(Peer reviewed; Journal article, 2022)R4-grade mooring chain steel specimens were subjected to alternating phases of saltwater corrosion and air fatigue to replicate seasonal load variations on chains in service. No significant difference in fatigue lifetimes ... -
The effect of long-term use on the Catch efficiency of Biodegradable gillnets
(Peer reviewed; Journal article, 2020)The effect of long-term use on the catch efficiency of biodegradable gillnets was investigated during commercial fishing trials and in controlled lab aging tests. The relative catch efficiency between biodegradable and ... -
The effect of low Cu additions on precipitate crystal structures in overaged Al-Mg-Si(-Cu) alloys
(Peer reviewed; Journal article, 2020)This study concerns the effect of low Cu additions (<0.1 at.%) on the precipitate crystal structure evolution in three Al-Mg-Si(-Cu) alloys during overageing. The evolution was assessed through a combination of atomic ... -
Effect of low temperature tensile properties on crack driving force for Arctic applications
(Peer reviewed; Journal article, 2017)Many petroleum companies expand their activities further north towards the Arctic region, resulting in design temperatures down to −60 °C, which is much lower than what is usual for most current petroleum installations. ... -
Effect of Manufacturing Techniques in Pressure Drop on Triple Periodical Minimal Surface Packings
(Peer reviewed; Journal article, 2021)Structured packings are important elements to enhance mass and heat transfer in the chemical industry. New techniques of manufacturing, like 3D printing, can create completely new families of solids used for this purpose. ... -
