Computational Fluid Dynamics Modeling Of Smoke Spread Due To Fire in Buildings

This research aims to analyze smoke contamination using computational fluid dynamics (CFD) software in high-level atrium. The reasons beyond the rise of this study are; the dangerous extent of smoke effects upon human beings as it is found to be a major lives threat in fire incidents. The choice of high-level atrium was due to its large construction rate worldwide and in Malaysia particularly as there are more than 200 shopping malls in Malaysia. The developed model will be altered various times according to the combination of parameters changed; therefore, many cases will be simulated in order to propose a new correlation that aid designers/engineers to produce safe designs. The objectives of this research are; investigate the behavior of smoke due to fire in upper balconies at an atrium and utilize (CFD) software, Fire Dynamics Simulator (FDS) in modelling fire incident. 36 cases will be simulated and evaluated for 3, 5, and 7 balcony buildings. The findings of this project show that smoke contamination increases with the increment of building height as well as the presence of down stand structures (brand display). Eventually, there are three correlations generated from the obtained results and it is recommended for engineers and architects to utilize them in designing safer Atrium in the future.
