1. 11. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Benjamin Waldeck; [2020]
   Keywords : Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

   Abstract : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. READ MORE

3. 12. The verification and validation of a probabilistic risk analysis method for road tunnels

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Kim Genberg; Karin Sandin; [2020]
   Keywords : Tunnels; fire; evacuation; probabilistic risk analysis; QRA; verification and validation; Technology and Engineering;

   Abstract : In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled.

4. 13. The Influence of Cavity Widths and Lateral Ventilation Conditions on the Fire Behaviour within a Non-Combustible Ventilated Façade System

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Daniel Fogerty; [2020]
   Keywords : Technology and Engineering;

   Abstract : Present uncertainties in key ventilation parameters, characterising the fire performance of facades, has necessitated clarification in the foundational understanding of the Fire Science Body of Knowledge. A test program conducted in collaboration between Lunds Universitet and the Kingspan Group, studied the influence of cavity widths and lateral ventilation conditions on the fire behaviour within Intermediate-scale ventilated façades following the ISO 13785-1 standards.

5. 14. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Andreas Lilja; [2020]
   Keywords : CFD; FDS; FEM; TASEF; EKS; Eurocode; Simulation; Fire; Balcony; CFD; FDS; FEM; TASEF; EKS; Eurokoderna; Simulering; Brand; Balkong;

   Abstract : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. READ MORE

6. 15. Study of semi-empirical methods for ship resistance calculations

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Emil Petersson; [2020]
   Keywords : ;

   Abstract : In the early ship design process a quick overview of which shipdesign that could be the optimal choice for the intended usage needsto be investigated. Therefore the feasibility and accuracy ofinterpolating between measurement data from model resistance serieswhen estimating unknown hulls were conducted. READ MORE
