Study of the Dynamics of Fire and Smoke Control in Case of Evacuation in High Buildings, Based on Continuous Model FDS+EVAC

To understand the fire behaviour depending on the structure of the building, it is extremely important, not only to analyse and interpret the ventilation systems, but also to understand the forms of support for smoke control and analyse the best strategy evacuation in case of emergency of zones of high flow of occupants.

With the evolution of hardware and software, the technique of numerical simulation has been widely applied in the simulation of reconstruction of fire, making it a useful tool in analyzing the design features, ultimately improving the speed of evacuation of occupants.

So this article is a brief review of the methods of smoke control based on 3D simulation of the dynamics of fire with a case study applied to a 21 story building with an area of 2060m (Technological Department of Wuhan University of Technology, Hubei-China). In order to introduce the study based on continuous model FDS+Evac, some examples of simulation scenarios of fire in one of the building stairwells are presented. Also, natural ventilation, pressurization and dilution, are simulated as tested, with the aim of obtaining the optimal solution. Furthermore, the results are analysed and compared. Finally, it is also addressing continuation studies.
