An Experimental Investigation of the Effect of Rust and Mechanical damage on the Maximum Experimental Safe Gap for Ethylene Gas Explosions
(Master thesis, 2012-05-31)Gas explosions are a great hazard in the industry where flammable substances are handled. Engines, switches and other electrical equipment can act like ignition sources where an explosive atmosphere is present. Possible ... -
Experimental Investigation of the Impedance Measurement Method for Detecting Dust and Gas Flames in a Flame Acceleration Tube. Development of Experimental Apparatus
(Master thesis, 2009-06-02)This thesis describes an experimental investigation of flame propagation in a 3.6-meter Flame Acceleration Tube (FAT) by the use of optical probes for flame detection and dust concentration measurements. The experiments ... -
Experimental Investigation of the Impedance Measurement Method for Detecting Dust and Gas Flames in a Flame Acceleration Tube. Development of Experimental Apparatus
(Master thesis, 2009-06-02)This master thesis describes an impedance measurement device built for investigating flame propagation in a Flame Acceleration Tube, FAT. This tube is 3.6 m long, and has been instrumented with thermocouples, pressure ... -
An Experimental Investigation of the Influence of Mechanical Damage and Rust on the Ability of Flame Gaps to Prevent Hydrogen Gas Explosion Transmission
(Master thesis, 2012-05-31)The present work investigates the influence of rusted and mechanical damaged flame gaps, and the ability of these flame gaps to prevent a hydrogen gas explosion transmission between an inner and outer explosion chamber. ... -
An Experimental Investigation of the Influence of Mechanical Damage, Rust and Dust on the Ability of Flame Gaps to Prevent Gas Explosion Transmission
(Master thesis, 2010-11-19)Potential ignition sources, such as motors, light switchers and relays that are located in an industrial area where an explosive atmosphere is a threat, must be designed in such a way that the ignition source does not ... -
Experimental investigation of the stable water isotope distribution in an Alpine lake environment (L-WAIVE)
(Journal article; Peer reviewed, 2021)In order to gain understanding on the vertical structure of atmospheric water vapour above mountain lakes and to assess its link with the isotopic composition of the lake water and with small-scale dynamics (i.e. valley ... -
Experimental investigation of wind farm flow effects
(Master thesis, 2022-01-17)A reasonable arrangement of wind turbines in a farm is essential for optimum energy efficiency and load reduction. In addition to the widely discussed wake interaction effects, the research community has recently debated ... -
An Experimental Investigation on the Effect of Nitrogen Enriched Air and Heat Transfer on the Maximum Experimental Safe Gap for Propane Gas Explosions
(Master thesis, 2012-06-15)Electrical apparatuses for use in potentially explosive gas atmospheres are required to be enclosed. There are two main requirements in the design of such enclosures. Firstly, they are required to withstand the pressure ... -
Experimental investigations of Magnetization processes in Chinese loess
(Doctoral thesis, 2011-11-25) -
Experimental methods to study the process of snow-ice formation induced by saltwater rise
(Master thesis, 2018-11-09)The Arctic region is experiencing a change from thick multiyear to much younger and thinner sea ice. In many places, increasing precipitation is leading to higher snow loads on young sea ice. Hence seawater can infiltrate ... -
Experimental model of plug formation in subsea pipelines
(Master thesis, 2022-06-01) -
Experimental modeling and novel therapeutic strategies in melanoma brain metastasis
(Doctoral thesis, 2015-06-09)Melanoma patients carry a high risk of developing brain metastases and improvements in survival are still measured in weeks or months. The aim of this thesis was to study the biology of melanoma brain metastasis and find ... -
Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs
(Peer reviewed; Journal article, 2014-08-14)It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ... -
Experimental Studies of N2 - and CO2-Foam Properties in Relation to Enhanced Oil Recovery Applications
(Doctoral thesis, 2015-06-01)Foams can do more than soften a beard or extinguish a fire. Foam also offers the oil industry better mobility control. The presence of a foaming agent in porous rocks can reduce the mobility of gas and water, stabilize the ... -
Experimental studies on the immune response to Ehrlich's ascites carcinoma
(Doctoral thesis, 1964-05-13) -
An Experimental Study of CO2 sequestration in saline aquifers and gas hydrates
(Master thesis, 2014-09-10)Processes related to the displacement of brine by CO2 were studied in core flood experiments in high-permeable, homogeneous Bentheim sandstone using a medical CT scanner. These processes are of high relevance for prediction ... -
Experimental study of diffusive oil recovery during low salinity waterflooding and miscible CO2 injection in sandstones and shales
(Master thesis, 2014-11-24)This experimental thesis presents a study of two diffusive EOR techniques; low salinity waterflooding in 2D sandstone silicon wafer micromodels and miscible CO2 injection in tight shale core samples. Tests were conducted ... -
An Experimental Study of Foam Flow in Fractured Systems of Increasing Size
(Master thesis, 2016-06-01)Although use of foam for gas mobility control is substantially covered in literature, large- scale field implementation is still absent in fractured reservoirs. Current understanding of foam behavior in fractured systems ... -
An Experimental Study of Foam Flow in Water Saturated Porous Media
(Master thesis, 2017-06-20)The amount of greenhouse gases in the atmosphere has increased significantly the last 250 years, causing a global temperature rise. CO2 emissions from fossil fuel combustion is a major contributor to greenhouse gas emissions, ... -
