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. ... -
Ein numerisk studie av ammoniakkspreiing i eit urbant område ved bruk av simuleringsverktøyet FLACS
(Master thesis, 2018-06-20)Ammoniakk er eit giftig stoff som kan føre til skade på menneske og dyr som vert utsett for det. Då store mengder ammoniakk vert frakta og lagra i urbane områder som væske under trykk, vil det ugjere ei stor fare for ... -
An Experimental Study of Pool Fires and Validation of Different CFD Fire Models
(Master thesis, 2011-06-06)Computer programs developed to predict a possible fire scenario is today an important tool when working with fire safety. In this context different Computational Fluid Dynamics models, so called CFD models, where the domain ... -
Interpretation of geometrical effects in consequence modelling. Comparison study between the commercial consequence assessment tools FLACS and PHAST for flammable gas dispersion
(Master thesis, 2014-04-02)Computational fluid dynamics and integral consequence modeling is today a crucial part of safety assessments worldwide. The models are widely used to predict the effects of ventilation patterns, hazardous gas dispersion, ... -
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 ... -
Sammenligning av spredningsmodellering med kodene PHAST og FLACS, for “tyngre en luft” gassjeter med horisontalt sammenstøt, og valideringssimuleringer av MUST forsøkene.
(Master thesis, 2011-01-20)Denne rapporten er et arbeid som sammenligner to dataverktøy, PHAST og FLACS vedrørende ulike spredningsscenarier for fluider, først og fremst tung-gassutslipp. Det er utført en rekke simuleringer som ligger til grunn for ... -
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 ...
