Course type: Third-cycle course
Teaching language: English
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.

Judgement and Approach
For a passing grade the doctoral student must adequately consider relevant scientific and ethical aspects related to design of underground structures.
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.
