Time-Dependent Effects of Glaze Ice on the Aerodynamic Characteristics of an Airfoil
(Journal article; Peer reviewed, 2018)The main objective of this study is to estimate the dynamic loads acting over a glaze-iced airfoil. This work studies the performance of unsteady Reynolds-averaged Navier-Stokes (URANS) simulations in predicting the ... -
Title: Comparative Life Cycle Assessment of a hydrogen fuel cell and diesel-powered high-speed passenger catamaran
(Master thesis, 2020)Store utslipps kutt er nødvendig for å overvinne forventet vekst i skipsfartsindustrien. CO2-utslippene fra denne sektoren kan være s˚a mye som 2,5 ganger høyere innen 2050 hvis ikke tiltak blir satt i gang (Smith et al. ... -
Tofase varmeovergang og strømningsfordeling i prosessteknisk utstyr
(Master thesis, 2007)Sammendrag del 1: Institutt for Energi- og Prosessteknikk ved NTNU har inngått et samarbeid med industrien for å utvikle et fordamperkjølerkonsept til smelteovnskjøling. Dette konseptet anvender boblekoking av et høytemperatur ... -
Tolman lengths and rigidity constants from free-energy functionals – General expressions and comparison of theories
(Journal article; Peer reviewed, 2019)The leading order terms in a curvature expansion of the surface tension, the Tolman length (first order), and rigidities (second order) have been shown to play an important role in the description of nucleation processes. ... -
Tolman lengths and rigidity constants of multicomponent fluids: Fundamental theory and numerical examples
(Journal article; Peer reviewed, 2018)The curvature dependence of the surface tension can be described by the Tolman length (first-order correction) and the rigidity constants (second-order corrections) through the Helfrich expansion. We present and explain ... -
Too much consumption or too high emissions intensities? Explaining the high consumption-based carbon footprints in the Nordic countries
(Peer reviewed; Journal article, 2022)Consumption-based carbon footprints have been widely used to examine how different demand-side solutions can reduce the emissions from personal consumption. This study not only utilized consumption-based carbon footprints ... -
Tool development for LCOE calculation for floating offshore wind
(Bachelor thesis, 2022)Lønnsomhet er viktig for å insentivere utviklingen av fornybar energiprosjekter. Flytende havvind er fortsatt i en begynnende fase, men forventes å gå inn i det grønne markedet med industriell og økonomisk styrke. Utjevnet ... -
Top-down spatially-explicit probabilistic estimation of building energy performance at a scale
(Peer reviewed; Journal article, 2021)Achieving the energy-related and environmental targets for nations and municipalities is largely dependent on the existing built stock. It plays a pivotal role in the accomplishment of these targets through the implementation ... -
Toward a sustainable energy system in China: Status and influencing factors
(Journal article; Peer reviewed, 2021)This paper focused on the endogenous and exogenous factors that affect China's sustainable energy system (SES). 19 Endogenous factors, from economic sustainability dimension, social sustainability dimension, environmental ... -
Toward high performance of zinc-air battery using hydrophobic carbon foam-based diffusion electrode
(Journal article; Peer reviewed, 2018)NaCl is used as template to form porous carbon during the carbonization procedure. It is found that the NaCl amount played an important role in the physical properties of hydrophobic carbon materials. When the current ... -
Toward Surfaces with Droplet Impact Robustness and Low Contact Angle Hysteresis
(Peer reviewed; Journal article, 2022)Superhydrophobic surfaces show excellent water repellent performance. However, liquid impalement occurs when a droplet impacts on the surface at high velocity. To achieve higher resistance to liquid impalement at the same ... -
Towards a circular phosphorus economy in Norway - Strategies for integrating agriculture and aquaculture at multiple scales
(Research report, 2023)Phosphorus is a building block for all life and therefore plays an essential role in food production. Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer, ... -
Towards a LCA Database for the Planning and Design of Zero-Emissions Neighborhoods
(Peer reviewed; Journal article, 2022)The integration of science-based knowledge on greenhouse gas (GHG) emissions into practice-based neighborhood design and planning is key to inform and implement climate mitigation strategies. LCA is a method that is commonly ... -
Towards a more climate-resilient agricultural sector in Norway
(Master thesis, 2023)Landbruk og klimaet påvirker hverandre i stor grad. Landbruket er svært avhengig av stabile økosystemer, samtidig som det er ansvarlig for 19-29% av globale drivhusgassutslipp og den viktigste driveren til biodiversitetstap ... -
Towards an engineering tool for the prediction of running ductile fractures in CO2 pipelines
(Peer reviewed; Journal article, 2023)A prerequisite for the deployment of CO2 capture and storage (CCS) is to establish a large network of high-pressure transport pipelines. It is then vital to assess new and existing pipeline designs for running ductile ... -
Towards comparable carbon credits: Harmonization of lca models of cellulosic biofuels
(Peer reviewed; Journal article, 2021)Decarbonization programs are being proposed worldwide to reduce greenhouse gas (GHG) emissions from transportation fuels, using Life Cycle Assessment (LCA) models or tools. Although such models are broadly accepted, varying ... -
Towards EU climate neutrality: Progress, policy gaps and opportunities
(Book, 2024)Based on an assessment of more than 80 indicators, we found that more efforts are needed across all sectors to achieve the EU climate objectives from 2030 to 2050, and particularly in buildings, transport, agriculture and ... -
Towards robust, authoritative assessments of environmental impacts embodied in trade: Current state and recommendations
