Students replicate wildfire behavior to help mitigate risk, improve safety
July 30, 2024
MOSCOW, Idaho 鈥� 果冻传媒麻豆社 students are developing a prototype to improve understanding of wildfire behavior聽and further risk mitigation and safety research.
The partnership includes the College of Engineering and College of Science. Engineering students designed and constructed a device that can produce embers for observing and testing ember-structure interactions in controlled environments and mimic real wildfire conditions.
鈥淭his isn鈥檛 just playing with fire,鈥� said Peter Wieber, a recent biological engineering graduate involved in the project. 鈥淲e鈥檙e providing a wildfire research tool for the world.鈥�
A total of 97,504 acres were consumed by wildfire in Idaho in 2023, according to a report by the Idaho Department of Environmental Quality. Impacts 鈥� including property damage, timber loss, exposure to wildfire smoke, watershed pollution, death and injury 鈥� are important factors behind the student-led innovation.
Embers are a natural byproduct of wildfires, playing a significant role as they can be carried long distances and ignite spot fires downwind. These embers pose a significant threat in the wildland-urban interface, where structures and undeveloped wildland meet, potentially causing loss of property, injury and fatalities.
Understanding the dynamics of ember interaction with both natural and human-made materials is crucial to mitigate wildfire expansion and identify and develop fire-resistant building materials, said Alistair Smith, project sponsor and professor and department chair in the U of I Department of Earth and Spatial Sciences.
鈥淭his device provides a safe way of understanding the mechanisms for how heat and fire impact everything from structures to plant physiology,鈥� Smith said.
Smith鈥檚 team includes physicists, fire ecologists, chemists, plant ecophysiologists and remote-sensing scientists all interested in improving the mechanistic understanding of fire in Earth environments.
The student design and prototype use a motorized auger woodchip feed system and propane flame to output a steady stream of embers for 15 minutes without refueling. Their device ensures accurate assessments while minimizing risks.
鈥淭his second-generation design is a significant step forward, specifically addressing areas for improvement identified in the first iteration,鈥� said Mark Roll, mechanical engineering faculty member and team mentor. 鈥淭he recent wildfires in New Mexico only highlight the pressing need for well-engineered fire-safety solutions informed by controlled testing.鈥�
The engineering student team includes Jackson Coleman of Boise, Caleb Hanson of Idaho Falls, Aleczander Smart of Caldwell, Cassidi Shindler of Colfax, Washington, and Wieber of Boise.
