Smoke Control through Ventilation Systems on the Fire-Induced Conditions in a Stairwell

Aristides Lopes da Silva, Shengwu Xiong, and Hussain Aamir
Abstract—To understand the fire behavior depending on the structure of the building, it is extremely important, not only to analyze and interpret the ventilation systems, but also to understand the forms of support for smoke control and analyze 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 and ventilation studies, making it a useful tool in analyzing the design features, ultimately improving the visibility of evacuation of occupants. In this article is proposed a model that examines design issues related to mechanical ventilation systems, particularly associated with pressurization systems of stairwells, and also analyses a potential alternative approach, namely, a model that involves the supply and exhaust of high rates of air streams, providing clean air into the stairwell and thus the possibility of maximum dilution of any fumes that may be present. In order to introduce the study based on continuous model FDS, some examples of fire simulation scenarios in one of the stairwells of a building are presented. Also, natural ventilation, pressurization and dilution, are simulated as tested, with the aim of obtaining the optimal solution. Furthermore, the results are analyzed and compared. Finally, it is also addressing continuation studies.

Index Terms—CFD simulations, dilution system, FDS code, fire tests, mechanical exhaust.
