The interaction between a ceiling jet and smoke detector
is being investigated with computational fluid dynamics
(CFD) modeling in order to better under aerosol entry
phenomena. The CFD modeling is performed in two stages.
The first stage simulates the bulk transport of smoke
from the fire to the detector location. The second stage
uses the ceiling jet conditions from the first stage as
an inlet boundary condition. The geometry of a smoke
detector and the fluid region in its immediate vicinity
are modeled in order to examine the nature of the
aerosol entry for the given inlet condition and
