Abstract
The QUIC (Quick Urban and Industrial Complex) model uses the Lagrangian random-walk method to determine the transport and dispersion of plumes. There are existing physics in the model for atmospheric aerosols, mainly for atmospheric deposition and dosage. QUIC-Fire and QUIC-SMOKE are sub-models that determine the extent of fire spread and production of smoke. This model is currently missing aerosol effects such as nucleation, condensation, and coagulation. The current research to integrate these effects into the model is focused on the coagulation of particulates released by combustion. The intent is to determine general coagulation equations for the QUIC model and ultimately apply them to PM2.5 particles, their concentration, and their impacts on plume behavior after a fire event.
