Abstract:
The purpose of this work is to study the coupling of the
one-dimensional pyrolysis model to the computational
fluid dynamics model for fire simulation. The large eddy
simulation of the gas phase flow is combined with the
combustion model using flame sheet approximation and a
finite volume model for radiation. The model is used to
predict the full-scale flame spread in a room with wood
linings. The performance of the model is studied by
comparing the predicted heat release rate, heat flux and
surface temperatures with measurements.
