Cover Story: Shown is a QUIC-Fire simulated smoke plume from a pine-forest wildfire. A simple, computationally-efficient surrogate model was created for predicting particulate emission factors for reduced-order simulations. Leveraging a database of detailed simulations, the surrogate model translates particle-formation phenomena to simple correlations connecting fire characteristics (flame length, gas velocities, and local oxygen concentrations) to local emission factors as well as estimate emitted particle size distributions. Emitted particles are subsequently transported and dispersed using QUIC-Plume, a plume trajectory model, with QUIC-Fire velocity fields.View this paper.

A simple, easy-to-evaluate, surrogate model was developed for predicting the particle emission source term in wildfire simulations. In creating this model, we conceptualized wildfire as a series of flamelets, and using this concept of flamelets, we d...

18 December 2019

Wildfires can result in significant social, environmental and economic losses. Fires in which dynamic fire behaviours (DFBs) occur contribute disproportionately to damage statistics. Little quantitative data on the frequency at which DFBs occur exist...
