On A New One-Dimensional Model to Describe Tunnel Fires

  • We present a model derived to describe tunnel fires. The model originates in a compressible description of the air in the tunnel. It takes into account the strong buoyancy forces and at the same time the small Mach-number of the airflow. We comment on the derivation, on analytical results and on numerical simulations of the model. The model has been validated using data from real tunnel fireWe present a model derived to describe tunnel fires. The model originates in a compressible description of the air in the tunnel.

It shows good agreement with the real situation.show moreshow less
