The critical ventilation velocity in tunnel fires — a computer simulation

  title={The critical ventilation velocity in tunnel fires — a computer simulation},
  author={Ching Chiang Hwang and James C. Edwards},
In ventilated tunnel fires, smoke and hot combustion products may form a layer near the ceiling and flow in the direction opposite to the ventilation stream. The existence of this reverse stratified flow has an important bearing on fire fighting and evacuation of underground mine roadways, tunnels and building corridors. In the present study, conducted by the National Institute for Occupational Safety and Health, a CFD program (fire dynamics simulator) based on large eddy simulations (LES) is… CONTINUE READING
