Models of Wildland Fire and Ember Spread
Kevin Speer, Bryan Quaife, Jie Sun
In this Chapter we explore the nature and theory of ember transport using observations from controlled laboratory settings, prescribed fire, and wildland fire. Specific examples an…
Statistical Models of Ember Wash and Their Impact on Wildfire Area Growth
Bryan Quaife, Kevin Speer
Wildfire spread is strongly influenced by the transport and ignition of embers. While long-range spotting driven by plume lofting has received significant attention, embers transpo…
Characterizing Turbulence at a Forest Edge: Comparing Sub-filter Scale Turbulence Models in Simulations of Flow over a Canopy
Dorianis M. Perez, Jesse M. Canfield, Rodman R. Linn +1
In wildfires, atmospheric turbulence plays a major role in the transfer of turbulent kinetic energy. Understanding how turbulence feeds back into a dynamical system is important, d…
Characterizing Turbulence at a Forest Edge: A Vorticity Budget Analysis around a Canopy
Dorianis M. Perez, Jesse M. Canfield, Rodman R. Linn +1
Vorticity is a key characteristic of flow patterns that determine wildland fire behavior, frontal evolution, and wind-canopy interaction. Investigating the role of vorticity in the…
