1. 1. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Paolo Bertoli; [2021]
   Nyckelord :Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

   Sammanfattning : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.

   Sammanfattning : This report contains an evaluation of three different methods for determining smoke filling in high enclosures with small areas. The methods are here called: temperature difference method, first indication of smoke method, and visibility of ten meters method. LÄS MER

4. 3. Brandteknisk riskvärdering av Stockholms stadsbibliotek

   L3-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Emma Andersson; Erika Bengtsson; Thomas Berg; Max Coxner; [2014]
   Nyckelord :Fire safety evaluation; Stockholm Public Library; Fire Dynamic Simulator; SIMULEX; evacuation; smoke filling; radiation; CFD; Technology and Engineering;

   Sammanfattning : This report is a fire safety evaluation of Stockholm Public Library. Using FDS5 and Simulex the library has been evaluated in regards to egress time and the time to untenable conditions. Certain criteria’s apply to when untenable conditions are reached; these include smoke layer height, radiation, visibility and temperature. LÄS MER

5. 4. Brandteknisk riskvärdering av Halmstadtravet

   L3-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Erik Lundborg; Frida Olin; Caroline Svederberg; Viktor Wahlström; [2014]
   Nyckelord :BBR; brandscenario; brandteknik; brandteknisk riskvärdering; BTR; effektutveckling; FDS; Halmstadtravet; kritiska förhållanden; känslighetsanalys; LTH; personsäkerhet; rökfyllnad; SIMULEX; travbana; utrymning; critical conditions; department of Fire Safety Engineering; evacuation; fire safety evaluation; fire scenarios; heat release rate; human safety; racetrack; sensitivity analysis; smoke filling; Technology and Engineering;

   Sammanfattning : The report is an examination element of the course Brandteknisk riskvärdering. The purpose of the report is to evaluate human safety of visitors in case of fire at the racetrack Halmstadtravet and suggest possible solutions if the human safety is deemed insufficient. The purpose is also to train the students in their engineering capability. LÄS MER

7. 5. Fermented sausage : product development at Lindell's Gårdsslakteri

   Master-uppsats, SLU/Dept. of Food Science

   Författare :Nina Mogren; [2011]
   Nyckelord :meat product; fermented sausage; food additive; food product development;

   Sammanfattning : Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company’s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer’s needs and expectations and thereby be more likely to succeed. LÄS MER
