In case of fire within a building or underground space (e.g. station, cavern or tunnel), smoke would generally rise and spread, potentially endangering escape routes. Computational Fluid Dynamics (CFD) can be employed to predict the likely movement of smoke, and to enable smoke extraction and ventilation facilities to be designed appropriately. Smoke modelling can also be used to estimate the tenability conditions in smoke-contaminated areas, and to compare the smoke spread to pedestrian movements during the evacuation phase. This allows an investigation as to whether safe evacuation of occupants is possible for the prescribed fire scenario.
We have extensive experience in modelling fire and smoke scenarios for a range of building types and underground spaces, in interpreting the results of the calculations, and in recommending any changes in smoke ventilation and evacuation routes that may be required.
