Influence of geometrical parameters on the hysteresis of flutter onset in confined configurations
(Peer reviewed; Journal article, 2022)The interaction between a flow and a flexible structure can provide fascinating insight into the vortex shedding phenomenon and any propagation and mixing characteristics, which relate to a plethora of applications such ... -
Spatial variation in household consumption-based carbon emission inventories for 1200 Japanese cities
(Peer reviewed; Journal article, 2020)Given that national pledges are likely insufficient to meet Paris greenhouse gas (GHG) reduction targets (Fawcett et al 2015 Science 350), increasingly actors at the city and state level are looking for options on how local ... -
Numerical approaches for thermochemical conversion of char
(Peer reviewed; Journal article, 2022)This paper gives a review of the current state of the art for numerical simulations of char conversion. In particular, it presents models that have been developed to describe the physical and chemical phenomena that ... -
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 ... -
Geo-referenced building stock analysis as a basis for local-level energy and climate mitigation strategies
(Peer reviewed; Journal article, 2022)A geo-referenced building stock model was used to analyse the energy and climate performance of the Knowledge Axis in Trondheim, Norway, by 2050. Strategies for energy upgrades, construction of more energy-efficient new ... -
Performance Improvements of Standalone Liquid Air Energy Storage
(Doctoral theses at NTNU;2022:375, Doctoral thesis, 2022)Due to the threat of climate change, our energy systems tend to adopt lower-carbon energy sources, such as renewables. In addition, our energy systems are likely to follow another trend from very large centralized industrial ... -
Monitoring and simulating material cycles and emissions at multiple scales: Case studies for aluminium
(Doctoral theses at NTNU;2022:386, Doctoral thesis, 2022)Metal cycles form the backbone of our modern societies but are also responsible for a large part of the anthropogenic greenhouse gas (GHG) emissions. The transition towards a more sustainable socio-economic metabolism will ... -
Evaluation of MBTSA technology for CO2 capture from waste-to-energy plants
(Journal article; Peer reviewed, 2022)Moving bed temperature swing adsorption (MBTSA) is a promising technology for CO2 capture from flue gases. In a MBTSA unit, a selective adsorbent material is circulated between a low-temperature stage where it removes CO2 ... -
Sonochemical dosimetry: A comparative study of Weissler, Fricke and terephthalic acid methods
(Peer reviewed; Journal article, 2021)Acoustic cavitation and sonochemical reactions play a significant role in various applications of ultrasound. A number of dosimetry methods are in practice to quantify the amount of radicals generated by acoustic cavitation. ... -
Assessing the potential of seasonal thermal storage for local energy systems: Case study for a neighborhood in Norway
(Peer reviewed; Journal article, 2022)District heating has an important role in the shift to carbon-neutral energy systems through enabling the use of heat sources that would otherwise be wasted to cover buildings’ heating demands. The availability of many ... -
Generating environmental sampling and testing data for micro- and nanoplastics for use in life cycle impact assessment
(Peer reviewed; Journal article, 2022)Ongoing efforts focus on quantifying plastic pollution and describing and estimating the related magnitude of exposure and impacts on human and environmental health. Data gathered during such work usually follows a receptor ... -
Global extinction probabilities of terrestrial, freshwater, and marine species groups for use in Life Cycle Assessment
(Peer reviewed; Journal article, 2022)Human activities put pressure on the natural environmental and the Life Cycle Assessment methodology (LCA) is becoming a more prevalent tool to assess the relevant environmental impacts from products and processes on ... -
Modeling and simulation of oil-free liquid-injected screw compressors using ammonia-water mixture as working fluid
(Chapter, 2022)This study investigates the compression process of an oil-free screw compressor with liquid injection for an absorption-compression heat pump (ACHP) with an ammonia-water mixture as working fluid. In recent years, several ... -

The effect of hydrogen enrichment, flame-flame interaction, confinement, and asymmetry on the acoustic response of a model can combustor
(Peer reviewed; Journal article, 2022)To maximise power density practical gas turbine combustion systems have several injectors which can lead to complex interactions between flames. However, our knowledge about the effect of flame-flame interactions on the ... -
Improvements in Demand-Controlled Ventilation to Reduce Energy Use and Improve Indoor Air Quality
(Doctoral theses at NTNU;2022:363, Doctoral thesis, 2022)Buildings have become more airtight and insulated over the last years––a response to the acute need to reduce building energy demands in cold climates. However, to secure satisfactory indoor air quality (IAQ) this has led ... -
Role of higher education in sustainability of water resources An assessment of institutions in India
(Journal article; Peer reviewed, 2020)The motivation behind this paper is to understand the status of water resources management education provided in higher education institutions (HEIs) in India and decipher gaps between what is taught and what is needed in ... -
Climate change mitigation potentials of biofuels produced from perennial crops and natural regrowth on abandoned and degraded cropland in Nordic countries
(Peer reviewed; Journal article, 2022)Bioenergy expansion is present in most climate change mitigation scenarios. The associated large land use changes have led to concerns on how bioenergy can be sustainably deployed. Promising win-win strategies include the ... -
