This paper discusses the design and use of an apparatus
for evaluating the effectiveness of liquid fire
suppression agents as possible replacements for halon
1301. The apparatus consists of a porous cylindrical
burner located in the test section of a vertical wind
tunnel and a droplet generation system. Liquid droplets
are injected into the flow stream and entrained upward
toward the burner for evaluation. The suppression
effectiveness is ranked based on the conditions at the
transition from one mode of flame (enveloped) to the
other (wake) established at the burner for a given fluid
application rate. The apparatus is currently being used
to test a variety of fluids.
