An experimental study of an ejector-boosted transcritical R744 refrigeration system including an exergy analysis
(Peer reviewed; Journal article, 2021)The field of refrigeration witness a massive transition in the supermarket with a strong focus reflected on energy consumption. The use of ejector allows for overcoming the significant exergy destruction lays on the expansion ... -
Experimental study of an offshore aquaculture cage concept
(Master thesis, 2023)Behov for bærekraftig matproduksjon øker betydelig i takt med en økt global befolkning og global oppvarming. Nye klimavennlige løsninger må integreres og utvikles for å møte den økende etterspørselen etter mat, hvor ... -
An experimental study of beam-columns subjected to combined torsion, bending and axial actions
(Doktor ingeniøravhandling;1995:66, Doctoral thesis, 1995)This report presents an investigation on the inelastic behaviour of steel I-section beam-columns under combinations of axial load, bending and torsion. The study is motivated by the lack of information on the ultimate ... -
Experimental study of bubble characteristics and heat transfer in subcooled flow boiling of R-134a
(Master thesis, 2013)Because of its high heat transfer efficiency, subcooled flow boiling can contribute to the miniaturization of subsea heat exchangers. An experimental investigation was conducted to study the parametric influence on the ... -
Experimental Study of Cement-Formation Bonding
(Master thesis, 2013)This experimental work is the continuation of the literature study of cement-formation bonding, done in the autumn semester. Cement-formation bonding has not been given special attention so far, in resolving the well ... -
Experimental study of channel flow with sinusoidal walls using stereo-PIV
(Master thesis, 2021)Et eksperiment har blitt designet for å utforske resultatene til Brostrøm, Holum, Akselsen og Ellingsen i første omgang, og masteroppgaven kan bli sett på som en fortsettelse av dette arbeidet (Brostrøm, 2020, ... -
Experimental Study of CO2 Solubility in Ionic Liquids and Polyethylene Glycols
(Master thesis, 2015)The parameter of density, viscosity are tested and fitted with the result of solubility measurement. With series of experiments, this chemical blend is considered with a good effect. The mixture of 50% tetrabutylphosphonium ... -
Experimental study of concrete-ice abrasion and concrete surface topography modification

Experimental study of current forces and deformations on a half ellipsoidal closed flexible fish cage
(Journal article; Peer reviewed, 2016)Closed flexible fish cages are proposed as a new concept in marine aquaculture, replacing the conventional net cages in order to meet ecological challenges related to fish lice and escapes. It is important to understand ... -
Experimental Study of Damper Position on Instabilities in an Annular Combustor
(Chapter, 2018)The present study experimentally investigates the effects of different circumferential damper configurations on the instabilities in an annular combustor. The combustor consists of multiple bluff body swirl stabilized ... -
Experimental study of density waves oscillations
(Master thesis, 2013)Nowadays, systems based on convective boiling flows are found in a wide variety of industrial applications, such as boiling water reactors, boilers, thermosiphons, heat exchangers, condenser, chemical reactors and some ... -
Experimental Study of Direct Tensile Strength in Sedimentary Rocks
(Master thesis, 2016)Tensile strength is an important parameter in rock mechanics and is amongst other things used as a criterion for initiation and propagation of fractures in hydraulic fracture modeling. The tensile strengths are determined ... -
Experimental study of dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 1: Flow patterns, phase distributions and pressure gradients
(Journal article; Peer reviewed, 2016)The study demonstrates how a disturbance of the flow can affect the pressure gradient and further needs a considerable development length to recover. This is of importance for experimental studies as well as industrial ... -
Experimental study of dispersed oil-water flow in a horizontal pipe with enhanced inlet mixing, Part 2: In-situ droplet measurements
(Journal article; Peer reviewed, 2016)Droplet size measurements in premixed oil-water flow are presented. Three traversable focused beam reflectance measurement probes (FBRM) positioned along the test section allowed for measuring averaged droplet size profiles ... -
