Fire, Smoke, and Simulations

smokeview1Scientists and engineers are adapting a NIST-developed computational model to re-create aspects of the fires that occurred following the terrorist attack on the World Trade Center. The model, Fire Dynamic Simulator, and a software package, called SmokeView, have been used previously to aid in the re-creation of building fires that resulted in firefighter fatalities. Preliminary calculations have demonstrated the model's ability to shed light on the impact of building geometry, fuel distribution, and wind conditions on the smoke and fire flows within and outside the trade towers. Such information may be helpful to firefighters in predicting the likely behavior of future large-scale fires in high-rise buildings.
