  1. 1. Fire Dynamics in Multi-Room Compartment Fires

    Author : Nils Johansson; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

    Abstract : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. READ MORE

  2. 2. Compartment Fire Temperature Calculations and Measurements

    University dissertation from Luleå University of Technology

    Author : Alexandra Byström; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fire temperature; heat transfer; FEM; calculation of temperature; temperature measurement; fire scenario; validation; flashover; Stålbyggnad; Steel Structures;

    Abstract : This thesis is devoted to heat transfer and fire dynamics in enclosures. It consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy, fire dynamics and specific fire scenarios that have been studied. READ MORE

  3. 3. Spread of smoke and fire gases via the ventilation system

    University dissertation from Division of Building Science, Lund University

    Author : Polina Gordonova; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fires; fire flow; fire pressure; fire simulation; smoke spread; ventilation ducts; brandteknik; brand; brandspridning; rökspridning; ventilation; ventilationskanaler; beräkningsmodeller; datorprogram; simulering; teori;

    Abstract : This thesis examines the problem of smoke spread via ventilation ducts to adjacent room(s) in case of a compartment fire. The main goal is to examine the possibility of operating the fans during different fires in four types of buildings (compartments, hospitals, offices and hotels) and to estimate the risk of smoke spread in different conditions..

  4. 4. Numerical experiments - a research method in fire science

    University dissertation from Department of Fire Safety Engineering and Systems Safety, Lund University

    Author : Nils Johansson; Lund University.; Lunds universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

    Abstract : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. READ MORE

  5. 5. Simulation of Combustion and Fire-Induced Flows in Enclosures

    University dissertation from Department of Fire Safety Engineering and Systems Safety, Lund University

    Author : Heimo Tuovinen; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cumbustion; Chemical kinetics; Flamelet model; CFD models; Fire-induced flows;

    Abstract : Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. READ MORE
