Exploring the use of nanofluids in pump-free systems for solar thermal applications
(Peer reviewed; Journal article, 2023)By using nanofluids as a working fluid in pump-free designs, thermal energy systems can become more efficient and have reduced maintenance costs, ultimately extending the system’s lifespan. In this paper, our goal is to ... -
Eco-friendly and low-cost nanofluid for direct absorption solar collectors
(Peer reviewed; Journal article, 2023)Nanofluids are promising receivers for solar collectors with volumetric absorption. These solar collectors are 1.2…1.4 times more efficient than conventional technology. However, most of the considered nanofluids are ... -
Saved by hydrogen? The public acceptance of onshore wind in Norway
(Peer reviewed; Journal article, 2023)Achieving the green energy transition is not without difficulty. This is also the case for the deployment of renewable energy infrastructures. Among these, onshore wind has often been contested. Taking the case of Norway ... -
Investigation of nanofluids in alkaline electrolytes: Stability, electrical properties, and hydrogen production
(Peer reviewed; Journal article, 2023)Utilizing solar energy efficiently and manufacturing hydrogen economically are the primary goals in the energy industry. In this paper, we present a novel method to solve both issues by exploiting the electrolysis of ... -
Direct absorption solar collector: Use of nanofluids and biodegradable colloids
(Peer reviewed; Journal article, 2023)In this paper, an experimental and numerical analysis was performed on both carbon black nanofluids and a biodegradable fluid in a novel pump-free direct absorption solar collector (DASC). In the experiments, the nanofluid ... -
Safe Vessel Operations – The Tacit Knowledge of Navigators
(Peer reviewed; Journal article, 2023)ABSTRACT: The collision regulations include several qualitative terms without providing guidance as to how these terms could be understood in quantitative terms. These terms must therefore be interpreted by navigators, ... -
Numerical Analysis of an Articulated Hybrid Offshore Wind Turbine Concept
(Peer reviewed; Journal article, 2023)The concept of a "hybrid offshore wind turbine" originated from articulated loading platforms (ALPS). In this study, we have developed a concept design for the major structural components. Orcaflex was used to create a ... -
Experiments on upstream induction and wake flow for multirotor wind turbines
(Peer reviewed; Journal article, 2023)Multirotor wind turbine concepts are increasingly discussed as cost-effective alternatives for floating wind energy installations. When multiple smaller rotors are installed next to each other, the individual rotors ... -
Cohesive collisions of particles in liquid media studied by CFD-DEM, video tracking, and Positron Emission Particle Tracking
(Peer reviewed; Journal article, 2023)This paper investigates the cohesive collision of ice in an oil phase at temperatures ranging from −15.7 °C to −0.3 °C. The new information on the coefficient of restitution (COR) was obtained using three different velocity ... -
Experimental and numerical investigation of direct absorption solar collectors (DASCs) based on carbon black nanofluids
(Peer reviewed; Journal article, 2023)Direct absorption solar collectors (DASCs) typically achieve high efficiency due to the volumetric heat absorption process facilitated by the working fluids. In this study, carbon black (CB) nanofluids were utilized as the ... -
