Abstract-When fire occurs, smoke is detrimental to human health and interrupts the evacuation process if it is not controlled properly. Due to the existence of beams in a building, smoke tends to stagnate near the obstacles and recirculates, further delaying the evacuation process. In the current study, Fire Dynamic Simulator (FDS) is employed as a numerical tool to simulate smoke propagation. The numerical result is then compared with the available experimental data obtained from the literature. It is found that the agreement between the numerical and experimental results is promising. From this study, it is shown that FDS can indeed be used to model the smoke propagation in an enclosed car park; hence, it can be utilised to generate other CFD models related to fire simulation.

This article deals with the state-of-the-art of experimental and numerical studies carried out regarding air pollutant dispersion in urban environments. Since the simulation of the dispersion field around buildings depends strongly on the correct simulation of the wind-flow structure, the studies performed during the past years on the wind-flow field around buildings are reviewed. This work also identifies errors that can produce poor results when numerically modelling wind flow and dispersion fields around buildings in urban environments. Finally, particular attention is paid to the practical guidelines developed by researchers to establish a common methodology for verification and validation of numerical simulations and/or to assist and support the users for a better implementation of the computational fluid dynamics (CFD) approach.

Since the dawn of history maritime transport was an essential part of human communication and development which mandates the rapid development of the ship industry. It was accompanied by disasters caused by several factors among them fire played an important role. Fire can cause structural damage which affects ship safety and smoke which is life threating to passengers and ship crow. Trapped smoke in ship compartments if not ventilated or released can reach higher temperatures leading to flashover situation which enable fire propagation. The FLUENT CFD calculations were performed to analyze smoke generation and propagation in closed ship compartments. The time to reach flashover is also calculated. Based on how sealed and tight the compartment is three different scenarios where studied in this analysis: running air-condition while compartment door is open, stopped air-condition while compartment door is closed, and finally running air-condition while compartment door is closed. The calculations show that, the last scenario which incorporates modified running air-condition scheme to mitigate smoke was the best scenario.
