| Abstract | In the event of a fire in a house, the occupants may be harmed by untenable conditions developed during the fire. The time to untenable conditions can be estimated using experimental studies or numerical simulations. Experimental studies usually provide realistic informa-tion but are expensive and time consuming. Numerical simulations, using validated models, can therefore be used to overcome these drawbacks and may also be used to help in the design of experimental setups. As part of a research project to evaluate life safety in houses, the Fire Risk Management Program at IRC/NRC has carried out numerical simulations to study fire performance of Canadian houses. The nu-merical simulations were conducted using the Fire Dy-namics Simulator (FDS) [1], a CFD model developed by NIST. As a first step, the effect of the grid sizes on the simulation results of the fire in a house was investi-gated in order to determine an optimum grid size that will be adopted for future simulation. Several fire sizes have been investigated and the optimum grid resolution has been found. The chosen grid resolution was then used to determine the time when conditions would be-come untenable, based on criteria found in the literature. This paper presents the details of the grid optimization study as well as the evaluation of life safety in houses. |
