Verification of Experimentally Determined Permeability and Form Coefficients of Al2O3 Ceramic Foam Filters (CFF) at High and Low Flow Velocity Using a CFD Model
(Journal article, 2018)Filtration using Ceramic Foam Filters (CFFs) is a method widely used to separate inclusions from molten aluminium. In the present work, the specific permeability and form drag coefficients of nominal 50 mm thick commercial ... -
Very sharp diffraction peak in nonglass-forming liquid with the formation of distorted tetraclusters
(Peer reviewed; Journal article, 2020)Understanding the liquid structure provides information that is crucial to uncovering the nature of the glass-liquid transition. We apply an aerodynamic levitation technique and high-energy X-rays to liquid (l)-Er2O3 to ... -
Vibrational spectroscopic study of pH dependent solvation at an Ge(100)-water interface during an electrode potential triggered surface termination transition.
(Journal article; Peer reviewed, 2018)The charge-dependent structure of interfacial water at the n-Ge(100)-aqueous perchlorate interface was studied by controlling the electrode potential. Specifically, a joint attenuated total reflection infrared spectroscopy ... -
Vinterdrift av 3G-kunstgressbaner: En undersøkelse av tungmetaller og salter i jord rundt en bane i Trøndelag
(Bachelor thesis, 2020)Varierende klimaforhold og stor etterspørsel for økt spilletid har ført til en drastisk økning i antall kunstgressbaner i Norge de siste tjue årene. Mesteparten av disse banene er 3G-baner som inneholder ifyll av gummigranulat. ... -
Vurdering av borevæske alternativer for Frigg feltutvikling
(Bachelor thesis, 2019)Valg av borevæsker er en vesentlig del av det teknologiske valget under planlegging av boreoperasjonen i feltutviklingsplanen. Den mest kostnadseffektive metoden er ønsket, men det miljømessige avtrykket er også et viktig ... -
