ING4006 Advanced Fire and Egress Modelling

Contents and structure

Fire development and its consequences for people and structures to be analyzed and modeled. Thermal load on structures and smoke spread  is modeled by CFD to provide information on available time for evacuation. Group behavior in fire and human response patterns during evacuation should be analyzed and discussed. Required evacuation time to be modeled and compared with available evacuation time. Modelling will form basis for the selection of impact reducing measures (barriers) so that the damage is limited.

Learning Outcome

Knowledge

Candidates

• can discuss and understand people and groups behaviour in fire
• can model and analyze design of escape routes, effect of toxic gases and reduced visibility
• can model fire -- under various useful conditions -- with the help of freely available softwares
• can understand mathematical models of fire

Skills

Candidates

• can make use of hand calculations to estimate the time for evacuation
• can use advanced simulation programs to calculate time for evacuation from different scenarios
