Large eddy simulations of a standard test fire (EN 54-9,
TF4) were carried out. The development of the
large-scale air movements and temperature fields
generated by the enclosure fires are calculated. In
additron, the smoke transport and time evolution of the
size distributton of smoke aerosol due to coagulation
arc also predicted. The mass and number densities of
smoke particles arc computed at a detector location, as
speci tied in the standard test fire procedure. Recent
measurements of the number and mass densities of smoke
using electrical aerosol spectrnmctry compared favorably
with the model predictions.
