Next generation models for predicting the behaviour of bushfires: Challenges and prospects

Bushfires occur on a scale that may be measured in kilometers.  However, a challenge faced in developing next generation bushfire models is to capture the significant contributions that small scale phenomena make to the propagation of bushfires.   

Flow Prediction Through Canopies

A simple model of flow through a tree canopy and comparison with large-eddy simulations.

Duncan Sutherland Conference Poster 2016

Operational fire models rely on wind reduction factors to relate the standard meteorological measured or forecast wind speed to the flame-height wind speeds within a tree canopy.

Rahul Wadhwani Conference Poster 2016

Firebrands are burning pieces of litter, for example, bark, leaf, and twigs.

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.
