Large-scale testing is necessary to verify a specific sprinkler’s performance in order for the sprinkler to become listed and approved. By using computational fluid dynamics, the cost and time of this certification process could be reduced. The goal of this project is to determine how accurately the Fire Dynamics Simulator (FDS) 6 can predict the distribution of water of an automatic fire sprinkler by inputting the manufacturer’s specifications and measured characteristics: spray angle, spray offset, initial velocity and droplet size. A sensitivity analysis was completed to document the relative importance of each model input in the FDS 6 simulation. Future testing should include simpler methods for obtaining the model inputs as well as a larger sample size of different fire sprinklers.
