General
  • English
  • If sufficient demand
Aim
  • The aim is that the postgraduate students (PhD students) should, after completion of the course, be able to understand physical principles related to fire development, ventilation and fire dynamics (visibility, gases, temperatures, heat fluxes, flame length, fire spread etc.) in underground structures. The students should also understand the principles for production of toxic species in underground structure fires and their effects on persons exposed to the fire gases and the smoke. Furthermore, they should be able to derive and apply mathematical methods relevant for the fire development, spread of fire and exposure to occupants present in the underground structure at the time of the fire. The aim of the course is also that the students should be able to understand important aspects of heat fluxes to constructions of underground structures as well as the effects of ventilation conditions on fire development in different scales.
Contents
  • The course is given to postgraduate students at the Division of Fire Safety Engineering, Lund University, as well as postgraduate students at other universities. The course includes seminars, lectures and exercises.
    The literature consists of the book Tunnel Fire Dynamics, written by Haukur Ingason, Ying Zhen Li and Anders Lönnermark 2015. The book covers fully the content of the course and gives necessary background to the problems to solve. This book include among other things generation of combustion products, heat and radiation, the effects of combustion products, heat and radiation, temperatures, heat release rates etc. Before each seminar the students read specific chapters given in the list below for individual seminars.
    Between seminars the students are supposed to work on assignments, which are discussed shortly on the following seminar. At the end of the course the students are supposed to apply the gained knowledge and analyze a typical case problem e.g. to explain the course of fire development in a tunnel.
    It is assumed that the student develops a simple model predicting the outcome for the chosen assignment. At the seminars the topic is introduced and then discussed.
    Further instructions and relevant chapters are provided below. Generally a short paper (max 2 A4 pages) shall be submitted prior to each seminar containing the author’s refection on the material for the seminar.
    A total of 8 seminars are included in the course, namely (reading instructions given in parenthesis):
    Seminar 1. Introduction to basic fire dynamics in underground structures: Fire development in vehicles, fire growth rates, fuel and ventilation control (chapters 2, 4 and 5),
    Introduction to individual project assignments is given in this Section 1.
    Seminar 2. – Environmental effects of fires in underground structures (combustion products, gas temperature, flame lengths), (Chapters 7, 8 and 9).
    Seminar 3. Heat flux and thermal resistance and fire spread. (Chapters 10 and 11)
    Seminar 4. Smoke stratification and ventilation, (Chapter 12 and 13),
    Seminar 5. Visibility and tenability (Chapters 14 and 15)
    Seminar 6. Calculation of FED, group work.
    Seminar 7. Introduction to CFD modelling in tunnels and scaling technique, (Chapters 17 and 18).
    Seminar 8. Presentation of project works.

    explain principles for fires in vehicles and how the fire progresses and the effects of ventilation on the process
    explain and derive engineering relationships for design fires, visibility, flame lengths, critical velocity, backlayering, stratification of smoke, production of smoke and toxic gases (tenability)
    use methods to predict the effects on persons exposed to combustion products, heat and radiation
    explain the Fractional Effective Dose (FED) and Fractional Effective Concentration (FEC) models used to predict incapacitation
    calculate heat exposure to tunnel structure and how it affects the load capacity
    understand the important parameters to consider in CFD calculations for tunnels
    understand scaling methods and techniques for fires in tunnels
    use models and engineering correlations to do a project work that relates to a fire case study in a tunnel
Competences and Skills
  • For a passing grade the doctoral student must
  • analyse a tunnel fire and relate them to survival of persons using FED/FEC analysis
    analyse a tunnel fire in terms of fire development, fire magnitude and production of combustion products, heat and radiation
    seek information (articles, reports, manuals, etc) about fire development, effect on humans from combustion products, heat and radiation, and heat exposure to structure and how it influence the load capacity
