Abstract:
A fire growth model has been developed to predict the
flame spread and total heat release rate of a fire in
the corner of a combustible lined room. Input data for
the combustible lining was developed using small-scale
test data from the ASTM E1354 cone calorimeter and ASTM
E1321 LIFT. The fire growth model includes a flame
spread model linked with a two zone compartment fire
model, CFAST Version 3.1.2 . The model was validated
against large-scale Navy and USCG ISO 9705 room test
data and large-scale open corner test data on a variety
of combustible materials. Using this model, the effects
of layer heating and lateral flame spread on fire growth
in a corner configuration were explored. Lateral flame
spread was found to be an important consideration in
large spaces (i.e., open corner) where layer heating was
not significant. In smaller compartments (i.e., ISO
9705), the effects of layer heating are significant and
lateral flame spread is less important.
