Cooling aerosols and changes in albedo counteract warming from CO2 and black carbon from forest bioenergy in Norway
(Journal article; Peer reviewed, 2018)Climate impacts of forest bioenergy result from a multitude of warming and cooling effects and vary by location and technology. While past bioenergy studies have analysed a limited number of climate-altering pollutants and ... -
Cooling of high power density electric machines
(Master thesis, 2022)Luftfartsindustrien bidrar med omtrent 4-5% av total drivhusgassutslipp. En overgang til elektriske fremdriftsmetoder kan bidra til å redusere utslipp, men gir flere utfordringer rundt termisk adferd. I denne oppgaven ble ... -
Cooling potential assessment for automated window operation algorithms
(Master thesis, 2022)CO2-utslipp og klimaendringer har vært et stadig viktigere tema ettersom global oppvarming allerede har vist observerbare effekter på miljøet. Mer ekstremvær, stigende havnivåer og hyppigere tørker og flom er noen av de ... -
Cooling Solutions for the First Norwegian Series of Permanent Magnet Machines
(Master thesis, 2014)SmartMotor AS has an ambition of developing a new series of permanent magnet (PM) machines. The aim is to offer one range of machines for marine applications such as propulsion, anchor and winches, and a separate range ... -
Cooling System for High Energy Efficient Electric Motors: Kjølesystemer for energieffektive elektriske motorer
(Master thesis, 2013)The development of an efficient cooling system for an axial magnetic flux machine was the subject of the presented master thesis. Throughout the study, an experimental model was designed which offers the possibility to ... -
Copper ore material footprints and transfers embodied in domestic and international trade of provinces in China
(Peer reviewed; Journal article, 2022)Copper is a critical material for development and plays a profound role in transitioning to a low-carbon future. China is the main copper consumer in recent decades that has a fast-growing domestic market accompanied by ... -
Correlation between standards and the lifetime commissioning
(Journal article; Peer reviewed, 2010)This paper reviews the applicability and drawbacks of available European and international standards related to lifetime commissioning, by structuring them into Norwegian commissioning procedures. The work describes research ... -
Correlation effects between turbulence and the conversion rate of pulverized char particles
(Journal article; Peer reviewed, 2017)The effect of turbulence on heterogeneous reactions on the surface of char particles embedded in a turbulent oxidizer, consisting of oxygen and carbon-dioxide, is in this work studied numerically. It is shown that for a ... -
Cost Efficient Industrial Heat Recovery through Heat Pumps
(Master thesis, 2016)Industrial waste heat often contains large amounts of useable energy that cannot be utilized in its current form, and has to be used together with a waste heating technology to become useful. With increasing energy prices ... -
Cost evaluation and life cycle assessment of biogas upgrading technologies for an anaerobic digestion case study in the United States
(Master thesis, 2017)Globally, around one third of the food produced is lost or wasted. Instead of landfilling or incinerating, organic municipal solid waste has increasingly been used in anaerobic digestion in order to produce biogas. The ... -
Cost Optimality of Energy Systems in Zero Emission Buildings in Early Design Phase
(Master thesis, 2014)Abstract During the uncontrolled consumption period the building sector has come to account one of the greatest proportions of greenhouse gas emissions and energy use in industrial countries. In this context, European ... -
Cost savings and CO2 emissions reduction potential in the German district heating system with demand response
(Peer reviewed; Journal article, 2021)Demand response (DR) has been an effective technique to maximize the proportion of renewable energies integrated into energy supply systems. This paper investigated the benefits of DR on three building types (apartment ... -
Cost-effective clean ammonia production using membrane-assisted autothermal reforming
(Peer reviewed; Journal article, 2020)Ammonia is a widely produced industrial chemical, primarily for use in the fertilizer industry. Recently, interest has also grown in ammonia as a carbon-free energy carrier because it is easier to store and transport than ... -
Coupled effects of wave and depth-dependent current interaction on loads on a bottom-fixed vertical slender cylinder
(Peer reviewed; Journal article, 2023)The coupled effects of waves and a subsurface current on the hydrodynamic loads on offshore slender structures in coastal water regions have been examined in this paper, especially the coupling of the weak nonlinearity of ... -
