1. Släckteknisk skillnad mellan mörkt och ljust släckpulver
Kandidat-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The purpose of the work was to investigate whether an extinguishing powder with a darker color other than white has an increased extinguishing effect when extinguishing a fire in an enclosure. In the experiments conducted, a conventional extinguishing powder was tested against a carbon black-dyed extinguishing powder with nitrogen or air as a propellant. LÄS MER
2. Studies on the performance of firefighter’s gas cooling
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. LÄS MER
3. Applicering av befintliga handberäkningsmetoder på tidsberoende brandförlopp
Kandidat-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The aim of this study is to investigate whether simple hand calculation methods are useful complements to CFD-simulations while calculating the temperature and height of the hot gas layer for transient fires. The analysis is based on evaluations of results from experiments, CFD-simulations and hand calculation methods. LÄS MER
4. Influence of geometry and ventilation boundaries on simulation of the flow outside a room set-up in laboratory environment
Master-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetSammanfattning : In this study, the results from simulations of two sets of a 1/2 scale ISO room (ISO 9705) experiments are presented. In the experiments, heptane in a tray was burned in the middle of the room. Five models with various levels of complexity and geometric detail are used. LÄS MER
5. The Classification System for Surface Lining Materials used in Buildings in Europe and Japan
Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetSammanfattning : This report summarizes the classification systems for surface lining materials in Europe and Japan. There is also a part including a discussion on differences, similarities and possible ways to link the two different systems together. In June 1994, an important agreement was made between the member countries in the European Community. LÄS MER
