Experimental and theoretical studies of rapid phase transitions in CO2
(Doctoral dissertations at the University of South-Eastern Norway;13, Doctoral thesis, 2018-10-19)Rapid depressurization and evaporation of a pressurized liquefied gas are phenomena of relevance to hazard identification and risk analysis in the process industry. Tank explosions and pipeline ruptures are accident scenarios ... -
Experimental Design and Modeling for Propylene Oxide - CO2–Poly (Propylene Carbonate) Solutions
(Journal article; Peer reviewed, 2018)In this research, experimental design was used to formulate the empirical models of viscosity and density of poly(propylene carbonate) (PPC), propylene oxide (PO), and carbon dioxide (CO2) solutions by designing experiments ... -
Experimental Evaluation of MIMO Observers and Model Based Controllers
(Master thesis, 2018)State estimators for MIMO systems and model based controllers are important for multivariable control. Many publications have presented results of multivariable control, however most of the results are obtained from ... -
Experimental Evidence for an Attractive p-φ Interaction
(Peer reviewed; Journal article, 2021)This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a ϕ meson. The result is obtained from two-particle correlations of combined p−ϕ ⊕ −p−ϕ pairs measured in ... -
Experimental infection of lambs with tick-borne encephalitis virus and co-infection with Anaplasma phagocytophilum.
(Journal article; Peer reviewed, 2019)Tick-borne encephalitis virus (TBEV) is a zoonotic pathogen which may cause tick-borne encephalitis (TBE) in humans and animals. More than 10,000 cases of TBE are reported annually in Europe and Asia. However, the knowledge ... -
Experimental investigation and simulation of ignition of fuel-air clouds with fuel mixtures of hydrogen and hydrogen-carrying fuels
(Master thesis, 2021)Hydrogen is playing an increasingly important role as the world moves to a low-carbon energy system, but combustion properties of this gas are very different from other hydrogen-carrying fuels that can lead to difficulties ... -
Experimental investigation of artificial snow production in marginal geographic conditions
(Master thesis, 2021)Dette arbeidet hadde som mål å utføre både litteratur og eksperimentell studie av kunstig snøproduksjon i marginale geografiske forhold. Det viktigste bak dannelsen av kunstig snø er vann som eksponeres for kald luft danner ... -
Experimental investigation of hydrogen-air explosions with a schlieren set-up
(Master thesis, 2015-09-18)Schlieren has been used in the visualization of shock waves since the beginning of the 20th century and is still highly actual in the research of shock waves and DDT. The goal of this study was to build a schlieren setup ... -
Experimental investigation of load exerted on a double-cone insert and effect of the insert on pressure along walls of a large-scale axisymmetrical silo
(Journal article; Peer reviewed, 2011-03-03)Applications of flow aid devices (commonly referred as inserts) improve the silo discharging mode. Considerable efforts have been made in finding best configurations between the inserts and silos to achieve the optimal ... -
Experimental measurements of diesel spray in an inert gas generator
(Master thesis, 2017)A 90° Y-jet atomizing nozzle with 3 bores was experimentally tested in a science facility at University College of Southeast Norway. The nozzle is producing a diesel fuel spray for a pilot flame in an IGG system for marine ... -
Experimental Methods in Economics and Psychology: A Comparison
(Journal article; Peer reviewed, 2015)This article compares the use of experiments as a research method in economics and psychology. We outline the most important differences between the two fields in terms of their use of experimental methods. The purpose of ... -
Experimental Study and CFD Modelling of Minimum Fluidization Velocity for Geldart A, B and D Particles
(Journal article; Peer reviewed, 2017)The aim of this study is to determine minimum fluidization velocity of three different particles which represent different Geldart classification groups and to compare the results with computational results. The experiments ... -
Experimental study and SEM-EDS analysis of agglomerates from gasification of biomass in fluidized beds
(Peer reviewed; Journal article, 2022)Fluidized bed gasification is an attractive conversion technology for biomass. However, processing biomass in fluidized beds suffers from ash related problems. In this work, bed agglomeration of wood pellets and grass ... -
Experimental study of agglomeration of grass pellets in fluidized bed gasification
(Chapter; Peer reviewed, 2020)The agglomeration tendency during gasification of grass pellets in a bubbling fluidized bed reactor was studied. Particle agglomeration occurs as a consequence of interactions between the bed particles and the biomass ash ... -
Experimental study of bubbling fluidized bed
(Master thesis, 2008-06)A series of experiments are performed in order to study the flow behaviour of bubbling fluidized bed. A two dimensional fluidized bed is built up with dimension 0.8 m (height) × 0.2 m (width) × 0.025 m (depth) and uniform ... -
