Wildfires are complex phenomenon. To understand
their spread mechanisms, physics based wildfire
models are developed here. Discontinuous fire
spread, i.e., spotting, is studied through a review
of historical wind-driven and post-earthquake fires.
Transport of various shapes of combusting firebrands
is modeled using momentum balance on the firebrand.
Firebrand trajectories are simulated in velocity and
thermal fields generated by the FIRETEC wildfire
model. Contiguous fire spread is modeled based on
energy conservation and detailed heat transfer
mechanisms. Predictions of contiguous fire spread
rates are compared to laboratory experiments and
prescribed fires.
