VIV in Free Spanning Pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:371, Doctoral thesis, 2013)Two important aspects of vortex induced vibrations (VIV) in free spanning pipelines are so far not satisfactorily understood; the complex interaction between in-line (IL) and cross- ow (CF) response, and the signicance of ... -
VIV suppression in 2D circular cylinders through staggered grooves: A numerical investigation at low Reynolds number
(Master thesis, 2023)Vortex-induced vibration (VIV), a ubiquitous fluid-structure interaction phenomenon, plays a crucial role in the operational safety and longevity of various engineering structures subjected to fluid flow, such as marine ... -
VOC emission rates in newly built and renovated buildings, and the influence of ventilation – a review and meta-analysis
(Journal article; Peer reviewed, 2018)Few field studies have evaluated ventilation strategies, such as temporarily increasing the ventilation rate, to counter the high pollutant-load from off-gassing of volatile compounds from new materials in these buildings. ... -
Void growth in calciumcarbonate filled PVC
(Master thesis, 2011)SIMLab has in recent years been developing a constitutive material model for polymer materials. Polymersoften experience volume change during plastic deformation, which is often related to damage in the material, such as ... -
Void nucleation and growth in mineral-filled PVC - An experimental and numerical study
(Journal article; Peer reviewed, 2014)The nucleation and growth of voids in mineral-filled PVC have been investigated through experimental and numerical studies. Uniaxial tensile specimens were deformed in tension to different elongation levels and then unloaded. ... -
Volatile Organic Components Adsorption on Activated Carbon
(Master thesis, 2022)Some volatile organic components may cause serious human health and environmental threats. These components are "global warming agents" that contribute to climate change. While the negative impact of methane and carbon ... -
Volla bru, Rv. 4 Roa - Jaren
(Bachelor thesis, 2009)Denne rapporten innholder statiske og armeringstekniske beregninger på en betongbru som er tenkt bygd på nye Rv. 4 i Lunner kommune. Ytre mål på brua er tidligere definert av konsulentbyrå og prosjektgruppens formål er å ... -
Voltage Sensor Fault Detection in Li-ion Battery Energy Storage Systems
(Chapter, 2022)Safe and optimal operation of battery energy storage systems requires correct measurement of voltage, current, and temperature. Therefore, fast and correct detection of sensor faults is of great importance. In this paper, ... -
Volume Control in the Surface Drilling Fluid System
(Master thesis, 2010)During drilling operations the mud pit volume varies quite a lot. These variations are unavoidable due to different short term factors such as tripping in and out of the hole and pump rate changes, and different long term ... -
Volume Free Strain Energy Density Method for Applications to Blunt V-Notches
(Peer reviewed; Journal article, 2020)This work investigates the application of the strain energy density method to rounded V-notches under mode I loading conditions and to components without stress concentrators through finite element models that do not involve ... -
Volume growth during uniaxial tension of particle-filled elastomers at various temperatures–Experiments and modelling
(Journal article; Peer reviewed, 2017)A common presumption for elastomeric material behaviour is incompressibility, however, the inclusion of filler particles might give rise to matrix-particle decohesion and subsequent volume growth. In this article, the ... -
Volumetric strain measurement of polymeric materials subjected to uniaxial tension
(Journal article; Peer reviewed, 2019)A novel method for measuring and calculating volumetric strain in circular cylindrical uniaxial tension samples made from polymeric materials is proposed. It is shown that special considerations must be taken when calculating ... -
Voluntary Speed Loss of Ships
(Master thesis, 2017)When a ship is caught in heavy seas, speed loss follows. This thesis focuses on the subjective part of speed loss; voluntary speed reductions to maintain the safety of the ship, the cargo and the people. The objective is ... -
Volunteered geographic information research in the first decade: a narrative review of selected journal articles in GIScience
(Peer reviewed; Journal article, 2020)More than 10 years have passed since the coining of the term volunteered geographic information (VGI) in 2007. This article presents the results of a review of the literature concerning VGI. A total of 346 articles published ... -
Volunteered Geographic Information Research in the First Decade: Visualizing and Analyzing the Author Connectedness of Selected Journal Articles in GIScience
(Peer reviewed; Journal article, 2020)Volunteered geographic information (VGI) has been widely explored by researchers for decision support in various application domains because the data are cost-effective to collect and their richness in volume and spatiotemporal ... -
Vortex dislocation mechanisms in the near wake of a step cylinder
(Peer reviewed; Journal article, 2020)Vortex interactions behind step cylinders with diameter ratio D/d = 2 and 2.4 at Reynolds number ( ReD ) 150 were investigated by directly solving the three-dimensional Navier–Stokes equations. In accordance with previous ... -
Vortex dynamics and flow patterns in a two-dimensional oscillatory lid-driven rectangular cavity
(Peer reviewed; Journal article, 2020)The vortex dynamics in a two-dimensional oscillatory lid-driven cavity with depth-to-width ratio 1:2 has been investigated, covering a wide range of Reynolds numbers and Stokes numbers where this flow is known to be in the ... -
Vortex dynamics of a jet at the pressure node in a standing wave
(Journal article; Peer reviewed, 2020)In this paper we investigate the vortex structure and dynamics formed in the near field of a turbulent axisymmetric jet subjected to transverse acoustic forcing. Full three-dimensional phase-averaged velocity measurements ... -
