Viscosity measurements of CO<inf>2</inf>-rich; CO<inf>2</inf> + N<inf>2</inf> and CO<inf>2</inf> + H<inf>2</inf> mixtures in gas or supercritical phase at temperatures between 273 and 473 K and pressures up to 8.7 MPa
(Peer reviewed; Journal article, 2022)New experimental viscosity data of three binary CO2-rich mixtures with approximate mole fractions of 0.93 CO2 + 0.07 H2, 0.80 CO2 + 0.20 H2, and 0.90 CO2 + 0.10 N2 are reported. The measurements were performed at four ... -

Viscosity, Density and Volatility of Binary Mixtures of Imidazole, 2-Methylimidazole, 2,4,5-Trimethylimidazole and 1,2,4,5-Tetramethylimidazole with Water
(Journal article; Peer reviewed, 2019)Experimental measurements and modeling of the density and viscosity of binary solutions of imidazole, 2-methylimidazole, 2,4,5-trimethylimidazole, and 1,2,4,5-tetramethylimidazole with water have been conducted. The ... -
Viscosity, structure and glass formationin the AlCl3-ZnCl2 system
(Dr. ingeniøravhandling, 0809-103X; 2001:36, Doctoral thesis, 2001)Thermodynamic, viscous and structural properties of melts and glasses in the AlCl3-ZnCl2 system have been investigated. The two pure components are fundamentally different in the molten state. Both metal atoms are four ... -
Viscosity-Induced Crossing of the Phantom Barrier
(Journal article; Peer reviewed, 2015)We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the ... -
Viscosity-induced crossing of the phantom divide in the dark cosmic fluid
(Journal article; Peer reviewed, 2013-12-10)Choosing various natural forms for the equation-of-state parameter w and the bulk viscosity ζ, we discuss how it is possible for a dark energy fluid to slide from the quintessence region across the divide w = −1 into the ... -
Viscous cosmology - Bulk viscosity in the cosmological context
(Master thesis, 2015)The main objective of this thesis has been to estimate the present value of the bulk viscosity of the cosmic fluid. The following list contains a summary of the main results found in the present work: -The bulk viscosity ... -
Viscous Cosmology for Early- and Late-Time Universe
(Journal article; Peer reviewed, 2017)From a hydrodynamicist’s point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (exluding special cases such ... -
Viscous coupled fluids in terms of a log-corrected equation-of-state
(Peer reviewed; Journal article, 2021)In this paper, we consider a class of cosmological fluids that possess properties analogous to those of crystalline solids undergoing isotropic deformations. Our research is based on a modified log-corrected power-law ... -
Viscous flow around a circular cylinder near a plane wall
(Master thesis, 2011)Marine pipelines placed at or near the seabed are exposed to currents and waves. In the presence of a sedimentary seabed, the interaction between the surrounding water motions and the pipeline may cause erosion of sediments ... -
Viscous flow around a simplified model of a Christmas tree
(Master thesis, 2016)In the petroleum industry, a Christmas tree is a structure consisting of valves and spools that sits atop an oil well. In order to better understand the forces acting on a Christmas tree during and after installation, ... -
Viscous Flow Around Finite Lenght Circular Cylinder
(Master thesis, 2012)Viscous flow around circular cylinders is a classical research topic in fluid dynamics with a vast amount of practical applications in the field of offshore marine technology. In the flow around cylinders of finite length, ... -
Viscous Flow Around Inclined Circular Cylinder
(Master thesis, 2017)Circular cylinder is of vital importance in the marine industry. The goal of this thesis is to study the physical phenomenon around the inclined circular cylinder as well as the forces acting on it. The study is mainly ... -
Viscous Phenomena and Entropy Production in the Early Universe
(Doctoral theses at NTNU;2017:197, Doctoral thesis, 2017)During the very first fraction of a second after the Big Bang, the Universe were populated by all the particles in the Standard Model of elementary particles: From the massive top quark to the massless photons and gluons. ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
(Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ... -

Visibilidades de crianças da infância
(Peer reviewed; Journal article, 2014)This article discusses the different meanings of ‘child’, ‘children’ or ‘childhood’ within different contexts, in order to analyze the relevance of what may be called visibility – or invisibility – of childhood. For the ... -
Visible light-exposed lignin facilitates cellulose solubilization by lytic polysaccharide monooxygenases
(Peer reviewed; Journal article, 2023)Lytic polysaccharide monooxygenases (LPMOs) catalyze oxidative cleavage of crystalline polysaccharides such as cellulose and are crucial for the conversion of plant biomass in Nature and in industrial applications. Sunlight ... -
Visible-Light-Driven Photochromism of Hexagonal Sodium Tungsten Bronze Nanorods
(Journal article; Peer reviewed, 2013)Single-crystalline sodium tungsten bronze (Na-WO3) nanorods with typical diameters of 10–200 nm and lengths of several micrometers were prepared via hydrothermal synthesis. The as-prepared Na-WO3 nanorods crystallized in ... -
