A review on disposal and utilization of phytoremediation plants containing heavy metals
(Peer reviewed; Journal article, 2021)The reasonable disposal of plant biomass containing heavy metals (HMs) is a difficult problem for the phytoremediation technology. This review summarizes current literature that introduces various disposal and utilization ... -
Review on erosion phenomenon, maintenance, and financial calculation of lifetime as an asset for Pelton turbines
(Peer reviewed; Journal article, 2023)Prevention of greenhouse emissionsis the top priority for all countries, which urges them to switch to renewable energy as much as possible. Hydropower is one of the renewables that have high flexibility and at the same ... -
Review on numerical techniques applied in impulse hydro turbines
(Peer reviewed; Journal article, 2020)Impulse turbines are widely used in hydropower plants around the world due to their high efficiency in a larger operating range compared to reaction turbines. State of the art Pelton turbines can give over 90% efficiency ... -
Review on reactor configurations for adsorption-based CO2 capture
(Peer reviewed; Journal article, 2021)Adsorption-based CO2 capture has enjoyed considerable research attention in recent years. Most of the research efforts focused on sorbent development to reduce the energy penalty. However, the use of suitable gas–solid ... -
Review: PEMFC Materials' Thermal Conductivity and Influence on Internal Temperature Profiles
(Journal article; Peer reviewed, 2017)The polymer electrolyte membrane fuel cell (PEMFC) is far from isothermal when in operation. This is well established both from experiments and from mathematical modelling. Over the last 15 years, the research field and ... -
Reviewing the potential for including habitat fragmentation to improve life cycle impact assessments for land use impacts on biodiversity
(Peer reviewed; Journal article, 2019)Purpose The biosphere is progressively subjected to a variety of pressures resulting from anthropogenic activities. Habitat conversion, resulting from anthropogenic land use, is considered the dominant factor driving ... -
Revisiting the reattachment regime: a closer look at tandem cylinder flow at Re=10000
(Peer reviewed; Journal article, 2022)Tandem cylinder flow comprises several different flow regimes. Within the reattachment regime, the development of the gap shear layers is of utmost importance to the flow, but has received little attention so far. Through ... -
Revolving flow of a fluid-particle suspension with suction
(Journal article; Peer reviewed, 2018)The three-dimensional revolving flow of a particle-fluid suspension above a plane surface is considered. The flow represents an extension of the classical Bödewadt flow to a two-fluid problem. The governing equations for ... -
Reynolds-averaged, scale-adaptive and large-Eddy simulations of pemixed bluff-body combustion using the Eddy dissipation concept
(Journal article, 2018)A lean premixed propane/air bluff-body stabilized flame (Volvo test rig) is calculated using the Scale-Adaptive Simulation turbulence model (SAS) and Large-Eddy simulations (LES) as well as the conventional Reynolds-averaged ... -
Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling
(Journal article; Peer reviewed, 2018)In petroleum drilling, aqueous Polyanionic Cellulose solutions (PAC) are often used as a drilling fluid model system in experimental laboratory studies to investigate cuttings transport. Cuttings transport refers to the ... -
Rising carbon inequality and its driving factors from 2005 to 2015
(Peer reviewed; Journal article, 2023)Carbon inequality is the gap in carbon footprints between the rich and the poor, reflecting an uneven distribution of wealth and mitigation responsibility. Whilst much is known about the level of inequality surrounding ... -
Road Planning and Route Alignment Selection Criteria in the Norwegian Context
(Journal article; Peer reviewed, 2019)This paper reveals the main factors that guide road alignment design process in Norway. The goal is to discover what constitutes the main priorities for road planners, how these priorities are ranked when it comes to ... -
