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…
Soft-Lubrication Drainage and Rupture in Particle-Driven Vesicles
Yuan-Nan Young, Bryan Quaife, Herve Nganguia +3
The deformation and rupture of a lipid vesicle due to the forced normal approach of an inclusion are essential for optimizing the design of magnetic giant unilamellar vesicles [mag…
The Ceiling Height of Wildland Fire Plumes in Sheared Boundary Layer Flow
Jie Sun, Kevin Speer, Bryan Quaife +2
Radar observations from a prescribed fire experiment reveal a large-scale, billow-like vorticity pair associated with the plume head at the onset of plume bending. The bending conf…
Fire Dynamic Vision: Image Segmentation and Tracking for Multi-Scale Fire and Plume Behavior
Daryn Sagel, Bryan Quaife
The increasing frequency and severity of wildfires highlight the need for accurate fire and plume spread models. We introduce an approach that effectively isolates and tracks fire…
