Abstract
This paper describes work done to improve and validate
the capability of fire dynamics simulator (FDS) to
predict the dynamics of water mist sprays. Three single
orifice and five multi-orifice spray heads are modeled
with FDS based on information on the flow-rate, spray
angle, operating pressure and experimentally determined
particle size distribution. The capability of FDS to
predict the drop size, velocity, mist flux and number
concentration profiles within the spray cone is assessed.
The effects of turbulence modeling on the predictions of
the spray dynamics is investigated. The capability of FDS
to predict the air entrainment by high-speed water sprays
is validated using experiments in rectangular channels
with open ends.
