  1. 21. Combination of CFD and evacuation models for determination of FED and FEC levels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Beom Jin Jeong; [2014]
    Keywords : evacuation; CFD; FED; FEC; FDS6; Technology and Engineering;

    Abstract : Previously developed methods to evaluate FED and FEC level via combination of CFD and evacuation simulation have been verified by new features of FDS6 and extended to fire cases involving common building materials. The FED levels calculated by the conversion factor [1] based on carbon monoxide are compared with the direct calculation by way of mass fraction of carbon monoxide, hydrogen cyanide and carbon dioxide.

  3. 22. Fire development in insulated compartements - Effects from improved thermal insulation

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Anna Back; [2012]
    Keywords : Fire development; thermal insulation; low energy buildings; lightweight ship constructions; FDS; brand; isolering; lågenergihus; fartyg.; Technology and Engineering;

    Abstract : New construction solutions, such as low energy buildings and lightweight ship constructions in FRP composite, are designed with more insulation than regular constructions. This may affect the fire development, leading to dangerous conditions for occupants and firemen. READ MORE

  4. 23. Influence of geometry and ventilation boundaries on simulation of the flow outside a room set-up in laboratory environment

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Parinaz Hemmati; [2012]
    Keywords : Complex geometry; FDS simulation; ½ scale ISO test; Heptane fire; Technology and Engineering;

    Abstract : In this study, the results from simulations of two sets of a 1/2 scale ISO room (ISO 9705) experiments are presented. In the experiments, heptane in a tray was burned in the middle of the room. Five models with various levels of complexity and geometric detail are used. READ MORE

  5. 24. A method of quantifying user uncertainty in FDS by using Monte Carlo analysis

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Tor Lindström; David Lund; [2009]
    Keywords : CFD; Computational fluid dynamics; Monte Carlo; Fire Dynamics Simulator; parallel computing; FDS; distributions; uncertainty; sensitivity analysis; Technology and Engineering;

    Abstract : Several hundred FDS simulations have been run using Monte Carlo analysis and probability distributions of input variables. The simulations have been run to investigate the propagation of uncertainty from model inputs to outputs in order to quantify uncertainties that could arise due to the choices of an FDS user.
