CFD-Model for the Photothermal Conversion Process in Ionic Nanofluids
(Master thesis, 2018-06-20)Harnessing energy from a sustainable source like the Sun may be one of the key solutions for the increasing demand of energy. However, conventional solar harvesters are relatively low efficient so that use of solar energy ... -
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. ... -
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 ... -
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 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
(Master thesis, 2018-06-20)Empty nose syndrome (ENS) is a rare complication of nasal surgery done to enlarge the internal nasal channels. The feeling of nasal obstruction despite patency is one of the most common symptoms among ENS patients. This ... -
Particle size distribution of methane hydrates and particle growth using a CFD-PBM model
(Master thesis, 2018-08-30)Gas hydrates are solid crystalline compounds that contain water and gas molecules, and can be considered to be a natural occurring phenomena located in enormous amounts around the world. Particle growth and agglomeration ... -
A study of temperature profiles in ceiling jets under horizontal unconfined ceilings with the CFD tools FLACS and FDS
(Master thesis, 2017-06-22)The key to controlling accidental fires, is early detection by the correct placement of devices such as smoke detectors and sprinkler systems. Smoke is accompanied by a temperature rise, brought about by the ceiling jet ... -
Vented gas and dust explosions - External explosions
(Master thesis, 2016-06-01)The use of explosion venting is a widely applied safety measure, mitigating the effects of an internal gas and dust explosion. Implementation of this safety measure does however not eliminate all risks and hazards associated ...
