Fire dynamics simulation of multiple ethanol pool fires

In this study, a well-known Computational Fluid Dynamics software, so-called Fire Dynamics Simulator (FDS), has been used to simulate multiple ethanol pool fire scenarios. Influences and reciprocal impacts in terms of dynamics and growth of the pool fires have been investigated. Heat release rates temperature and flame shapes have been monitored as the main outputs of the simulations. Based on the simulation results, it can be concluded that the amounts of mass burning rate, the radiation energy and the pool fire flame height were significantly higher in multiple pool fires, when compared with the theoretical values obtained by the mere summation of single pool fires. Furthermore, the effects of different grid sizes on the accuracy of the pool fire simulations have also been investigated and are discussed.
