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 ... -
Experimental Study of Displacement Mechanisms in Microbial Improved Oil Recovery Processes
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:187, Doctoral thesis, 2010)The Microbial Improved Oil Recovery (MIOR) project has been defined at the Norwegian University of Science and Technology (NTNU). It is a cooperative project between the Department of Petroleum Engineering and Applied ... -
Experimental study of displacement of viscous oil in pipes by water
(Master thesis, 2013)This study is specifically concerned with the understanding of real restart procedure that is very crucial for prediction of oil-water columns displacement after un-expected shut down at water-viscous crude oil transportation. ... -
EXPERIMENTAL STUDY OF DRILLING MUD RHEOLOGY AND ITS EFFECT ON CUTTINGS TRANSPORT
(Master thesis, 2012)To determine the carrying capacity of the drilling fluid, also determine the settling velocities of the drilling cuttlings. To produce the Reynold's number experimentally. -
Experimental study of drilling riser and wellhead force by small scale testing
(Peer reviewed; Journal article, 2022)Small-scale model tests of a drilling riser were conducted, aiming at a better understanding of the mechanical transfer of forces from the drilling riser to the wellhead. The tests were conducted in a water tank with ... -
Experimental study of effectiveness of robotic cleaning for fish-processing plants
(Journal article; Peer reviewed, 2019)This paper presents the development and experimental testing of the effectiveness of a robotic cleaning system for fish processing plants. The processing of fish introduces a substantial risk of bacterial contamination, ... -
Experimental Study of Flow of Nanocellulose in Porous Media for Enhanced Oil Recovery Application
(Doctoral theses at NTNU;2019:339, Doctoral thesis, 2019) -
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
