Characterization of the MIL-F-24385F Nozzle

Abstract

Aqueous Film Forming Foam has been a fire suppression agent in use for nearly forty years. During this period, there has been little emphasis on characterizing the flow from nozzles that have a throw of only a few meters. With environmental concerns starting to appear, it is important to understand how the foam behaves. The research presented in this document attempts to quantify the mass flux and momentum of the foam. This was done using both experimental data and hand calculations. A range of nozzle angles were examined in an attempt to set bounds of the minimum and maximum expected values.
