AbstractIn this paper we investigate the ability of the Fire Dynamics Simulator (FDS), a Computational Fluid dynamics (CFD) fire model, to predict the heat release rate of polyurethane foam and the resulting spread of products of combustion in a residential building. The results from FDS are compared with data from open-air fire experiments conducted using two sections of a sofa mock-up, which were constructed entirely out of polyurethane foam. The burning rate of a sofa is characterized as a fast growing fire. We also present the results of a simulation using the FDS of a fast growing fire in a room on the first storey of a three-storey house. The numerical simulation of the fire in the three-storey house indicated that the opening of the stairwell doors allows toxic gases in the form of CO2 and CO to move to the upper floor. This contaminated the upper floors and rendered them life threatening to the occupants.
