The cautionary principle in risk management: Foundation and practical use
(Peer reviewed; Journal article, 2019)The precautionary principle is well known among scientists, politicians and the public in general. However, the closely related and broader cautionary principle is not so often referred to. Whereas the precautionary principle ... -
Cavity Size Effects on the Adsorption of CO2 on Pillar[n]arene Structures: A Density Functional Theory Study
(Peer reviewed; Journal article, 2023-08)Carbon dioxide (CO2) is the main greenhouse gas that contributes to the global warming. Therefore, CO2 adsorption is very urgent in the fight to limit global warming below 1.5 degrees Celsius. In this report, the interaction ... -
CCNA-Based Communication Technology Courses
(Peer reviewed; Journal article, 2020-04)Many study programs include courses on communication technology. All these courses explain the basis of communication technology, but they have different levels of detail depending on the study program and the related ... -
cdem: A macOS program for discrete element modeling of tectonic structures
(Peer reviewed; Journal article, 2023-08)cdem is a macOS document-based application for two-dimensional discrete element modeling of tectonic structures and their associated deformation. Documents encapsulate simulations that can be run and explored simultaneously. ... -
Cement Placement: An Overview of Fluid Displacement Techniques and Modelling
(Peer reviewed; Journal article, 2021-01)During drilling operations, effective displacement of fluids can provide high-quality cementing jobs, ensuring zonal isolation and strong bonding of cement with casing and formation. Poor cement placements due to incomplete ... -
Cement properties characterization from a section retrieved from an oil production well after 33 years of downhole exposure
(Peer reviewed; Journal article, 2021)A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions ... -
Certification as support for resilience? Behind the curtains of a certification body — a qualitative study
(Peer reviewed; Journal article, 2020)Certification in healthcare often involves independent private sector bodies performing legally required or voluntary external assurance activities. These certification practices are embedded in international standards ... -

Cfd analysis of low frequency oscillations in Newtonian and non-Newtonian fluids in a vertical pipe
(Peer reviewed; Journal article, 2019)The effect of vertically imposed, low frequency oscillations on the rheology of shear-thinning non- Newtonian fluids are studied numerically by computational fluid dynamics (CFD). Both Newtonian (water) and inelastic ... -
CFD investigation of blind-tee effects on flow mixing mechanism in subsea pipelines
(Peer reviewed; Journal article, 2022)Blind tees are widely used in subsea pipelines to enhance the mixing conditions of oil and gas products, but their structural design still relies on experience. In this paper, a series of numerical investigations have been ... -
CFD Investigation on Hydrodynamic Resistance of a Novel Subsea Shuttle Tanker
(Peer reviewed; Journal article, 2021-12)The Subsea Shuttle Tanker (SST) was proposed by Equinor as an alternative to subsea pipelines and surface tankers for the transportation of liquid carbon dioxide (CO2) from existing offshore/land facilities to marginal ... -
CFD investigation on scour beneath different configurations of piggyback pipelines under steady current flow
(Peer reviewed; Journal article, 2022)Scour beneath piggyback pipelines laid on a sandy seabed is numerically investigated by solving two-dimensional (2D) Unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The fluid flow and the sediment transport are ... -
CFD investigations of scour beneath a submarine pipeline with the effect of upward seepage
(Peer reviewed; Journal article, 2020-12)A numerical model of scour beneath subsea structures considering the effect of upward seepage in the seabed is proposed. A small seepage can cause significant changes to the hydrodynamic force on the bed surface and stability ... -
CFD simulations of a suspension bridge deck for different deck shapes with railings and vortex mitigating devices
(Peer reviewed; Journal article, 2019)Aerodynamic response of a single-box suspension bridge girder is investigated using CFD simulations. The importance of including railings and vortex mitigating devices such as guide vanes and a spoiler in the simulations ... -
CFD Simulations of the Propagation of Free-Surface Waves Past Two Side-By-Side Fixed Squares with a Narrow Gap
(Peer reviewed; Journal article, 2019)Two-dimensional computational fluid dynamics (CFD) simulations are carried out to investigate the gap resonance phenomenon that occurs when free-surface waves travel past twin squares in tandem. The volume of fluid method ... -
CFD simulations of violent breaking wave impacts on a vertical wall using a two-phase compressible solver
(Peer reviewed; Journal article, 2019)Four different types of breaking wave impacts on a vertical wall are simulated using a two-dimensional two-phase Computational Fluid Dynamic (CFD) model. Air is considered as an isentropic ideal gas without solving an ... -
