Comparison of burning velocity differences in a numerical explosion simulator
(Master thesis, 2014-06-02)A verification study of the two flame models in the numerical explosion simulation tool FLACS has been conducted. The beta flame model, and the SIF flame model has been tested in a 1D-channel at different time step sizes. ... -
Digital twin of a hydraulic accumulator for virtual detection of subsea leaks
(Master thesis, 2019-06-14)In cooperation with OneSubsea, this thesis investigates the reasons behind a sudden pressure drop occurring in hydraulic systems during operation of hydraulic accumulators. The thesis also addresses the challenge of detecting ... -
Effect of Water Mist Suppression System in Engine Room: Case Study of Fire in The Cruise Liner MS Nordlys
(Master thesis, 2014-06-02)In the 1980s ozone layer depleting was a major concern for the environmentalists. Halon was used as a fire extinguishing agent until it was banned in the early 1990's. The industry was therefore forced to find other solutions ... -
Eulerian CFD Model of Direct Absorption Solar Collector with Nanofluid
(Master thesis, 2019-12-13)Solar energy is the most promising source of renewable energy. However, the solar energy harvesting process has relatively low efficiency, while the use of solar energy is challenging. Direct Absorption Solar Collectors ... -

Investigating Wave Loads and Energy of a Spherical Object Using Numerical and Experimental Methods
(Master thesis, 2023-11-20)The world is undergoing massive changes due to climate change. To combat this, renewable energy sources are required. Whereas solar, wind, and hydropower are viable alternatives, wave power offers more stability and is a ... -
Investigation of Particle Trajectories and Flow Patterns in a Hydrocyclone by Positron Emission Particle Tracking (PEPT)
(Master thesis, 2012-05-31)Cyclone separators are widely used for separation of solids or droplets from gaseous or liquid fluids in several industries. Cyclones can be used for many purposes and each cyclone can be fitted to its area of use. In the ... -
Numerical Investigation of a Radially Cooled Turbine Guide Vane Using Air and Steam as a Cooling Medium
(Master thesis, 2021-06-01)Gas turbine performance is closely linked to the turbine inlet temperature, which in turn is limited by the turbine guide vanes ability to withstand the massive thermal loads. To improve the efficiency in modern high-temperature ... -

Numerical prediction of erosion in a choke valve
(Master thesis, 2019-06-25)Erosion wear in pipelines due to multiphase flows is a well-known problem in the petroleum production and transport industries. There are several different ways to predict the erosion damage on the system investigated. ... -
Numerical simulations of the flow and plugging behaviour of hydrate particles
(Master thesis, 2010-05-06)Abstract The main hydrate mitigation used by the industry today is to avoid formation at all cost. Avoidance of hydrate formation is made possible by use of inhibitors such as methanol or glycol. These are so called ... -
A numerical study of ammonia dispersion in an industrial area with the CFD tool FLACS
(Master thesis, 2018-06-20)As the use of ammonia increases, knowledge about dispersion patterns and dispersion tendencies is of enhanced importance. Due to its toxic nature, very few realistic experiments of ammonia dispersion in complex situations ... -
A Numerical Study of Empty Nose Syndrome: an Evaluation of Nasal Aerodynamics
