CFD is used to predict Fire growth, smoke flow movement and also compartment temperatures, and hence can be used to develop complete fire models. Presently the study of behaviour of fire is carried out using Computational Fluid Dynamics, CFD, which is considered to be the most sophisticated and advanced technique in this area. This was because of the industrial revolution and a new era in Fire, which would lead to massive destruction of life and property. While the most destructive fire and the beginnings of Fire safety can be traced back to ancient Rome, this discipline emerged as a separate branch of engineering only in the 20th century. Finally, the results of the thermocouples were compared to the actual experiment done by one of the universities researchers.įire Safety Engineering is the branch of engineering which uses science and engineering concepts for the protection of people and their property, whether living or non living against the hazardous effects of fire and smoke.
Furthermore, the air inlet, the extraction system, and the temperature thermocouples were also simulated. Using these two, first the fire rig was designed employing the best possible accuracy, and then the burning of the Heptane sample was simulated. The project was done using the Fire Dynamics Simulator, FDS, one of the most advanced and powerful CFD programs and Pyrosim, an interactive tool for FDS developed by thunderhead engineering team. In the present models, the various features in this area like the ignition and convection in the pool, are over predicted and very much simplified, giving inaccurate results. The aim was to draw attention to the discrepancies between the expected and the observed results, to the engineers designing the CFD simulation software for fire modelling, suggesting them to give more consideration to the small pool fires growth design. In this project, the burning of Heptane Sample in the fire rig, used in the University of Leeds labs, was simulated and studied.
