Workshop – Engineering calculations in tunnel fires

Workshop in engineering correlations for tunnel fire safety

Date: March 13, 2018 (One day prior to ISTSS 2018)
Time: 10 – 16
LocationRISE Resaearch Institutes of Sweden in Borås, Sweden
Price:  SEK 3000 + taxes (Sign up in conjunction with registration)

As the knowledge in fire dynamics in tunnels increases there is a need to introduce and learn more about new engineering calculations models for consultants and other stakeholders. In order to present the latest knowledge and methods RISE will offer a one day workshop prior to the ISTSS 2018 conference.

The aim is that the participants should be able to use the latest engineering models for calculation of fire development, smoke control and fire dynamics in underground structures. The participants will also obtain good understanding of the principles for production of toxic species in underground structure fires and their effects on persons exposed to the fire gases and the smoke.

Knowledge and Understanding
The main knowledge gain will be on how to:

• describe the relevant course of fire development and fire dynamics in underground structures
• explain principles for fires in vehicles, how the fire progresses and the effects of ventilation on the process
• explain and use engineering relationships for design fires, visibility, flame lengths, critical velocity, backlayering, stratification of smoke, gas temperature, heat flux, fire spread, and production of smoke and toxic species in the fire gases
• use methods to predict the effects of combustion products, heat and radiation on persons; explain the Fractional Effective Dose (FED) and Fractional Effective Concentration (FEC) models used to predict incapacitation and what occurs when human body is exposed to it.
• Training in using some of the most important equations on flame lengths, critical velocity, visibility and toxicity.

Content
The course is aimed for practicing engineers and other stakeholders working with fire safety in underground constructions.

The literature consists of the book Tunnel Fire Dynamics, written by Haukur Ingason, Ying Zhen Li and Anders Lönnermark 2015. The book fully covers the contents of the course and gives necessary background to the problems to solve.
