The flow of smoke under beamed ceilings is simulated
using a field model. This work was performed in order
to confirm that fire detector response can be evaluated
using computational data obtained from numerical
simulations as well as laboratory data obtained from
experiments. The field model is verified for this
application by showing that its temperature predictions
match experimental results obtained by Heskestad and
Delichatsios. Line plots are presented which show that
the numerical and experimental temperature measurements
are in good agreement. Contour plots are also presented
that show the temperature distribution in the channels
formed by the ceiling beams. Finally some preliminary
results involving the effect of beam depth on smoke flow
