Abstract
Abstract The aim of the present study was to estimate the prediction performance of a FDS (Fire Dynamic Simulator)to simulate the fire behaviors and suppression characteristics by operating a water-mist. Rosin-Rammler/log-normaldistribution function was used to determine the initial droplet distribution of water-mist and the effects of its modelconstant were considered. In addition, the simulation models were validated by a comparison of the predicted firesuppression characteristics with water-mist injection pressures to the previous experiments, and the thermal flow behaviors and gaseous concentration variations were analyzed. The results showed that water-mists with the same mean diameter were affected by the characteristics of the droplet size distribution, which have different size and velocity distributions at the downstream location. The fire simulations conducted in this study determine the initial droplet size distribution tuned to the base of the spray characteristics measured by previous experiments. The simulation results showed good agreement with the previous measurements for temperature variations and fire suppression characteristics. In addition, it was confirmed that the FDS simulation with a water-mist operation suppliesuseful details on estimations of the thermal flow fields and gaseous concentration under water mist operation conditions.
