Simulated rate-of-spread of a grassfire propagating under a tree canopy

  • Simulations of a fire entering, propagating under and leaving a tree canopy are conducted using FDS [1], a physics-based model.
  • The presence of a tree canopy effects the wind speed, which in turn effects the rate-of-spread of a fire.
  • From the simulated data we extract the average sub-canopy wind speeds in the absence of a fire and measure the rate-of-spread of a fire.
  • This is the first step to testing the wind-reduction factor approach used in current operational models.
