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.
