The modelling of extinguishment of fires still represents a significant challenge. As part of an effort to predict fire spread and extinguishment using water sprays we are developing a CFD model of fire spread. This paper deals with the description of the CFD model, the solid pyrolysis model (wood in this case) and the coupling of these models. Results are compared with experimental data from cone calorimeter tests and the model is shown to give good agreement. The sensitivity of the calculated results to uncertain parameters is also considered.
