摘要: In this study, we conducted an FDS numerical simulation for the purpose of carrying out a basic assessment usefulness water spray fire extinguishing. We analyzed effect securing stability in temperature and smoke density case according to intensities (20MW, 50MW) changes wind speed. When there was no speed tunnels, it effective safety people because cooling system had excellent on reducing temperatures densities there. The higher intensity is, less has flows. air current exists its disturbs stratification lowers visibility degree during evacuation. Therefore, extinguishing should be put into action only after take shelter fire.
