1. 1. Brandgasfyllnadsförlopp av en affärslokal - En valideringsstudie med Fire Dynamics Simulator

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Shamim Ahmed; [2016]
   Nyckelord :FDS; Fire Dynamics Simulator; simulation; under ventilated; combustion efficiency; ceiling jet; retail store; outer boundary; grid independent; combustion gas temperature; Technology and Engineering;

   Sammanfattning : Prediction of the spread of combustion gases from a fire is a major area of interest when analyzing buildings from a safety point of view. Hence programs with this aim are continuously being evaluated for the estimation of their validity. LÄS MER

   Sammanfattning : This report evaluates a first response with water against an underventilated fire with imminent risk of backdraft occurrence. The report is based on a literature review followed by 35 experiments conducted in a shipping container. LÄS MER

4. 3. Risks in using CFD-codes for analytical fire-based design in buildings with a focus on FDS:s handling of under-ventilated fires

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Anders Björklund; [2009]
   Nyckelord :validation; usage; reviewer; simulation; uncertainty; FDS; fire; under-ventilated; combustion; CFD; risks.; Technology and Engineering;

   Sammanfattning : The use of CFD-models as an engineering tool for fire based analytical design of buildings has increased over the last few years. The reason for this is partly that the legislation allows for analytical dimensioning but also because the legislation demands a high degree of verification for the analytical dimensioning. LÄS MER
