In the present study, numerical simulation has been performed to investigate the flow characteristics around the injecting nozzles which are the key parts of water mist fire suppression system. In the water mist fire suppression system (WMFSS), the fine mist droplets smaller than 1,000μmissued from the water mist nozzles suppress the fire plume by the direct cooling, oxygen displacement and attenuation of thermal radiation. For simulation of flow characteristics, the commercial CFD software, named as CFX and FLUENT, were used with the proper modeling. CFX was applied for analyzing the internal flow and FLUENT was applied for analyzing the external flow of water mist nozzles. The flow characteristics of the water mist nozzle found out in this study could be used for predicting the performance of the water mist nozzles for the fire suppression system.
