Experimental Study of Fluid-Structure Interaction in a Simplified Geometry of the Human Upper Airways
(Master thesis, 2015)OSAS (Obstructive Sleep Apnoe Syndrome) is a sleep related breathing disorder caused by repetitive collapses of the pharyngeal walls during sleep. The objective of this project is to supply experimental data to validate ... -
Experimental Study of Formation Damage during Underbalanced-Drilling in Naturally Fractured Formations
(Journal article; Peer reviewed, 2011)This paper describes an experimental investigation of formation damage in a fractured carbonate core sample under underbalanced drilling (UBD) conditions. A major portion of this study has concentrated on problems which ... -
Experimental Study of Fracture Toughness in Sedimentary Rocks
(Master thesis, 2016)This master thesis details the determination of mode I (tensile) fracture toughness, KIC, using the International Society of Rock Mechanics (ISRM) Chevron Bend (CB) method on three sedimentary rock types. Fracture toughness ... -
Experimental Study of High-Pressure Gas Injection Using Optical Methods
(Master thesis, 2018)This thesis first presents the role of LNG as a potential means to reduce marine emissions and get international shipping into compliance with new regulations set by regulatory authorities. An overview of different gas ... -
Experimental Study of Hydraulic Accumulator Discharge
(Master thesis, 2018)This thesis aims to identify the behaviour of a 4 l hydraulic bladder accumulator undergoing discharge under various conditions and ultimately shed some light on irregularities that OneSubsea Processing is experiencing ... -
Experimental Study of Hydrodynamic Loads on Ventilated Plates Near the Free Surface
(Master thesis, 2020)De hydrodynamiske kreftene på forenklede strukturer blir studert for å undersøke hvordan krefter varierer med porøsitet og nedsenking, samt gi en sammenligning mellom harmoniske oscillasjoner og bølger. Tvungne oscillasjoner ... -
Experimental Study of Ignition Delay, Combustion, and NO Emission Characteristics of Hydrogenated Vegetable Oil
(Journal article; Peer reviewed, 2019)In this article, a comparative study of hydrogenated vegetable oil (HVO) and diesel was performed in two constant volume combustion rigs and an optical accessible compression-ignited chamber (OACIC). Ignition, combustion, ... -
Experimental study of installation procedure and volume estimation of tarpaulin for chemical treatment of fish in floating cages
(Journal article; Peer reviewed, 2017)In the salmon industry chemical delousing is done by enclosing the cage in a tarpaulin, and then mixing the chemical agent in the enclosed water volume. Correct dosage is important to obtain the wanted effect, and in order ... -
Experimental study of Isobutane (R600a) evaporation in microfinned and smooth tubes
(Chapter, 2020)Heat transfer coefficient and pressure drop of Isobutane (R600a) in an internally enhanced tube has been experimentally measured and compared to a smooth tube with the same outer diameter of 5 mm. The effects of mass flux ... -
Experimental Study of Low Salinity Waterflooding and its Effect on Wettability
(Master thesis, 2011)Many low salinity waterflooding studies have been performed, both in the laboratory and on the reservoir scale, over the last decades. These studies have proven that, under the right conditions, it is possible to get an ... -
