In the aluminum industry, forming is an important process step that introduces dislocations in the material. To investigate the effect of dislocation retention after ageing on 6xxx-series alloys, a non-heat-treatable 5005 alloy was selected to measure the change in mechanical properties due to...
Directed energy deposition (DED) processes have a great potential for ship building industry to reduce the lead time of ship part supply. However, ship parts such as propellers and impellers have critical requirements on material's properties and component's performance. To ensure the exploitation...
In the automotive industry, there is a drive to reduce environmental impact, energy consumption, and costs related to the manufacturing of forged aluminum suspension components. The replacement of extruded stock with cast forging stock is one option that offers substantial potential for such savings...
A medium-scale hydrogen distribution chain, 3 tpd, is investigated for distribution in compressed gaseous form or in liquid form. The evaluation is complex and depends on factors like the upstream production and conditioning, the value chain energy efficiency, costs, chain flexibility, end user...
Humanitarian design is a term that can be used to describe the process of designing products, services or systems for populations affected by natural and/or man-made disasters. At the intersection between humanitarian action and design, lie new skills to be taught and opportunities to launch a new...
We present a framework for integrated experiments and simulations of tracer transport in heterogeneous porous media using digital twin technology. The physical asset in our setup is a meter-scale FluidFlower rig. The digital twin consists of a traditional physics-based forward simulation tool and a...
The electrical resistivity of reservoir rocks, according to Archie’s law, is very sensitive to changes in fluid saturation. Consequently, time-lapse resistivity anomalies due to CO2 storage within subsurface reservoirs can be detected by controlled source electromagnetic (CSEM) repeat surveying...
As electricity price volatility increases in Europe's transition to a net-zero society, power producers are forced to fully utilize the flexibility of their assets to time the markets in a profitable way. For hydropower producers in cascaded systems, a key challenge is to accurately include the...
Hydrogen is the leading candidate for achieving the goal of decarbonization and making countries energy-independent in the long term. However, spreading hydrogen in different sectors faces various issues, including safety: its flammability characteristics and the ability to permeate and embrittle...
Bioremediering av oljeforurensede strender kan være det beste (og eneste) alternativet i øde og sensitive områder. Målet med prosjektet er å få bedre kunnskap om hvordan tilsats av næringsstoffer kan øke biodegraderingen av olje i strandsedimenter. Denne rapporten inneholder en kort oppsummering...
This study presents an interdisciplinary approach to analyze different transition pathways towards the sustainable development of a low-carbon society, focusing on Norway as a case. The study bridges a socio-technical perspective on sustainability transitions with techno-economic energy systems and...
Thermodynamic properties of homogeneous fluids in the metastable and unstable regions are needed to describe confined fluids, interfaces, nucleating embryos and estimate critical mass flow rates. The most accurate equations of state (EoS) called multiparameter EoS, have a second, non-physical...
