Keywords: Fire Dynamic Simulator, Evacuation Simulation, Smoke Movement, Fractional Effective Dose
In this study spread of smoke from a possible fire in a University building and evacuation time of occupants were simulated. Fire dynamic simulation (FDS) that have done for natural and forced smoke evacuation with different scenarios, at the same time, evacuation simulations have also been done for various scenarios for different exits at the building. While occupants move through changing CO, CO2, and O2 concentrations, Fractional Effective Dose (FED) was gathered to obtain results from both simulations. FED results were evaluated for poisoning risk of occupants. According to comparative results, the combination of scenarios that forced smoke evacuation by fan and evacuation of occupants from all exits at the basement of the building has the lowest FED value. On the other hand, depending on fire source and smoke movement, sometimes it is not possible for occupants to use all exits. Therefore, evacuation simulation has been done separately from each exit, and evaluated with all FDS results.

Journal of Applied Fluid Mechanics

The Journal of Applied Fluid Mechanics (JAFM) is an international, peer-reviewed journal which covers a wide range of theoretical, numerical and experimental aspects in fluid mechanics. The emphasis is on the applications in different engineering fields rather than on pure mathematical or physical aspects in fluid mechanics. Although many high quality journals pertaining to different aspects of fluid mechanics presently exist, research in the field is rapidly escalating.
