Abstract
A prediction of the thermal response of a steel beam installed beneath a
ceiling and exposed to a localized fire source was performed by using
CFD model. The validity of this calculation has been verified by results
of experiments. Concerning the heat flux, the difference between
analytical results and experimental values increases with increasing
dimensionless heat release rate QHB*≡Q/ρCPT0 g1/2HB5/2.
In the case of the lower flange, the difference between the analytical
result and experimental value increases rapidly over the range of QHB*
from 0.3 to 0.5, reaching the maximum value of about 27(kW/m²). From
the results of the investigation, it has become clear that the
prediction is possible with a practical accuracy about the convection
part of heat transfer. However, it is necessary to model minutely about
combustion and radiation.
