Abstract

Computational Fluid Dynamics (CFD) programmes have found widespread use in the combustion and fire science community. These programmes make it possible to take into account phenomena that earlier models could not describe; a typical example being the movement of the smoke in a room. Furthermore, an increase in accuracy is expected when using CFD for the calculation of fire development, production of toxic gasses as well as the formation and motion of visibility reducing smoke particles. However not everyone is convinced of the suitability of these CFD techniques. The critics say that CFD programmes, in the worst case, may give erroneous results and that the calculation times are too long to be useful in practical fire safety engineering. This article takes a practical view on the use of CFD programmes for fire simulation by looking at two widely used models, SOFIE and FDS.
