Abstract

Numerical simulation has been performed to investigate the mist flow characteristics through the fire suppression nozzles for the design purposes. The commercial softwares, FLUENT and the fire dynamic simulator, FDS with the proper modelings were chosen as the numerical tools. In order to find optimal conditions in sense of the main performances of nozzles, the spray characteristics were analyzed both inside and outside of the nozzles. Geometric factors of the injecting orifices, i.e., diameter and chamfered angle were chosen as the simulation parameters for design application. From the present numerical results, 1.0c nozzles, whose orifice-diameter was 1 mm, having the chamfered angles were shown as the best performance of the fire suppression.
