   Nyckelord :Tunnelbränder; FDS; handberäkning; branddynamik; brandexperiment Tunnel fires; CFD; hand calculations; fire dynamics; fire experiment; Technology and Engineering;

   Sammanfattning : The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. LÄS MER

3. 2. Vägbeläggningens inverkan på brandeffekten vid tunnelbränder

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

   Författare :Niclas von Essen; Max Faye-Wevle; [2004]
   Nyckelord :tunnel; CFD; conecalorimeter; Asphalt; concrete; fire; truck; Technology and Engineering;

   Sammanfattning : The objective of this work was to examine the impact on evacuation conditions of the road surface material in tunnel fires. The road materials were tested in a conecalorimeter and the results were then used in CFD-simulations. The simulated truck fires in the tunnel were chosen in accordance with E. Paté-Cornell’s Quasi Worst Case. LÄS MER
