Experimental study of the heat transfer problem in expansion devices in CO2 refrigeration systems
(Journal article; Peer reviewed, 2019)Two expansion devices designed for CO2 refrigeration systems namely, capillary tube and fixed-geometry ejector were experimentally tested in the SINTEF/NTNU laboratory in Trondheim, Norway to determine the influence of ... -
Experimental study on a CO2-solid-gas-flow-based ultra-low temperature cascade refrigeration system
(Journal article; Peer reviewed, 2011) -
Experimental Study on Charcoal Production from Woody Biomass
(Journal article; Peer reviewed, 2016)In the present work, effects of process conditions on char and fixed carbon yields from four woody biomasses were studied. The influence of the particle size, sample mass, and pressure on experimental values of char and ... -
Experimental study on high pressure combustion of decomposed ammonia: How can ammonia be best used in a gas turbine?
(Chapter; Peer reviewed, 2021)Hydrogen, a carbon-free fuel, is a challenging gas to transport and store, but that can be solved by producing ammonia, a worldwide commonly distributed chemical. Ideally, ammonia should be used directly on site as a fuel, ... -
Experimental study on the effect of pressure on single and two stage combustion of decomposed ammonia (NH3-H2-N2) blends over a swirl stabilized burner
(Peer reviewed; Journal article, 2024)Ammonia (NH3) is a practical hydrogen vector for gas turbine power generation, but struggles to be deployed commercially due to many unresolved technical and fundamental challenges. This experimental investigation focuses ... -
Experimental study on the effect of soil moisture content on critical temperature rise for typical cable backfill materials
(Peer reviewed; Journal article, 2022)The increased utilization of power grid requires operating power cables close to their thermal limit. Buried power cables in such condition experience thermal instability where thermal resistance increases as the moisture ... -
Experiments and modelling of choked flow of CO2 in orifices and nozzles
(Peer reviewed; Journal article, 2022)In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ... -
Experiments and modelling of two-phase transient flow during pipeline depressurization of CO2 with various N2 compositions
(Journal article; Peer reviewed, 2014)Pressure-release experiments of CO2 with impurity contents of 10, 20 and 30 mol% nitrogen have been executed. The experimental investigations were performed in a 140 m long horizontal tube with an inner diameter of 10 mm. ... -
Expert Elicitation on Wind Farm Control
(Peer reviewed; Journal article, 2020)Wind farm control is an active and growing field of research in which the control actions of individual turbines in a farm are coordinated, accounting for inter-turbine aerodynamic interaction, to improve the overall ... -
Exploring household's flexibility of smart shifting atomic loads to improve power grid operation and cost efficiency
(International Conference on the European Energy Market;2020, Chapter; Peer reviewed, 2020)This paper explores the possibilities of shifting certain household consumer-based loads in time, to reduce unnecessary load peaks to the grid which again can cause challenges for Distribution System Operators (DSOs). ... -
