Modelling the dynamics of wildfires is very computationally challenging. Although three-dimensional\ computational fluid dynamics\ (CFD) models have been successfully applied to wildfires, the\ computational time\ required makes them currently impractical for operational usage. In this study, we develop a two-dimensional\ propagation model\ coupled to a {\textquoteleft}pyrogenic{\textquoteright}\ potential flowformulation representing the inflow of air generated by the fire. This model can accurately replicate features of fires previously unable to be simulated using current\ two-dimensional models, including development of a fire line into a parabolic shape, attraction between nearby fires and the observed closing behaviour of {\textquoteleft}V{\textquoteright} shaped fires. The model is compared to\ experimental resultswith good agreement. The pyrogenic potential model is orders of magnitude faster than a full\ CFD\ model, and could be used for improved operational wildfire prediction.
