  1. 11. FDS-simuleringar av anlagd brand på utsida av en fasad på enplansbyggnad med ventilerad

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonatan Blomstrand; [2015]
    Nyckelord :Anlagd brand; enplansbyggnad; ventilerad takfot; Fire Dynamics Simulator; FDS; arson fire; one storey building; ventilation opening; eave; Technology and Engineering;

    Sammanfattning : In this thesis three methods to predict smoke spread thorough small ventilation openings for the CFD field model FDS 5 are evaluated. The methods have been applied to several experiments where smoke spread in to the attic through ventilation openings in the eave have been studied. LÄS MER

  3. 12. The Impact of Fiber-Reinforced Polymer Constructions on Risk Level onboard Large Passenger Ships

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Anders Lynner; Josip Novacic; [2015]
    Nyckelord :Lightweight materials; fiber-reinforced polymer; FRP; fire safety; evacuation; ship; fire dynamics simulator; FDS; critical conditions; corridor; cabin; risk; Lättviktsmaterial; brandsäkerhet; utrymning; fartyg; kritiska förhållanden; korridor; kabin; risk.; Technology and Engineering;

    Sammanfattning : The main objective of this project was to determine how a FRP composite structure performs compared to a steel structure in regard to fire safety and risk level during an evacuation. More specifically the objective was to study how the differences in the thermal properties influence the smoke layer height, visibility and the temperature of the gases in the early stages of a fire.

    Nyckelord :CFD; SIMULEX; FDS; Fire Dynamic Simulator; Helsingborg Arena; Brandteknisk Riskvärdering; Idrottsarena; utrymning; rökfyllnad; riskanalys; Technology and Engineering;

    Sammanfattning : In this report the fire-safety of Helsingborg Arena is analysed and evaluated. This has been done considering the safety of the people evacuating the building in case of a fire. LÄS MER

  5. 14. CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Maher Al Taweel; [2013]
    Nyckelord :cold downdraughts; radiation; underfloor heating; surface temperature; air velocities; glass facades; CFD Star-CCM ; kallras; strålningsdrag; golvvärme; yttemperatur; lufthastigeter; glasfasader; CFD Star-CCM ;

    Sammanfattning : Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. LÄS MER

  7. 15. Brandteknisk riskvärdering av Sollentuna centrum

    L3-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Emma Dahlstrand; Anders Egilsson; Oskar Jansson; Tomas Ringdén; [2011]
    Nyckelord :kritiska förhållanden; CFD; effektutveckling; brand; Sollentuna centrum; Brandteknisk riskvärdering; utrymning; personsäkerhet; Simulex; Detact QS; @Risk.; Technology and Engineering;

    Sammanfattning : This report is written as a part of the course Fire Safety Evaluation at Lund University. The purpose of the report is to evaluate the fire safety of Sollentuna centrum. Sollentuna centrum is a mall north of Stockholm that has 18 000 to 19 000 customers per day. The focus is mainly on evacuation and human safety. LÄS MER
