Jeremiah Crocker, P.E. from Tyco Fire Protection Products will be presenting on Droplet Characterization Using Direct Imaging Techniques.
The ability to accurately measure sprinkler spray characteristics is necessary to validate predictive modeling tools such as Fire Dynamic Simulator (FDS), in turn leading to better predictions of the spray’s impact on the fire environment. Better predictions of sprinklered fires in FDS coupled with a better understanding of the impact of deflector changes will also eventually help to streamline the development of new fire suppression products. The pertinent spray characteristics include droplet size, droplet velocity, ligament breakup distance and flux distribution. Of these, droplet size is a particularly important variable for both modeling accuracy and fire suppression capabilities of the spray.
