Burning up: CU researchers use unique tunnel to study wildfires
Associate Professor Peter Hamlington leads the project. His group develops computational tools which allow researchers to understand how fire reacts at a variety of scales. Associate Professor Greg Rieker's team, including PhD student Amanda Makowiecki, developed and built the 鈥淲indCline鈥 鈥 a wind tunnel that can tilt up and down. They did so in consultation with Aerospace Engineering Assistant Professor John Farnsworth. The tunnel allows researchers to study how various fuels react to different conditions and allows for the study of emissions in a controlled setting using laser sensors.
Rieker and Hamlington said wind tunnels are traditionally used in studies of airplanes and car aerodynamics, but this sloping wind tunnel designed for wildfire research is the only of its kind anywhere in the world. It enables the CU College of Engineering and Applied Science team to reliably reproduce natural wildfire conditions in a way that has not previously been possible.
鈥淲ildfires contribute to property damage and environmental impacts from emissions to possible groundwater contamination,鈥 said Hamlington, who is part of the Department of Mechanical Engineering. 鈥淭he tools we are bringing to bear on this problem are new for any type of combustion research, so we are taking the latest and greatest from one field and applying it to another. We are unique in the field of combustion research, so we are unique in the field of wildfire research.鈥
Researchers are being asked to help understand these events from many perspectives.
The WindCline was originally constructed through a research award from the to examine the environmental impacts of prescribed burns on DoD property. Hamlington said the $1.1 million project uses adaptive mesh simulations and frequency comb laser diagnostics to give detailed info about many aspects of the fire.
鈥淯ltimately, the proposed research will bring together two cutting-edge technologies, simulations using adaptive mesh refinement and frequency-comb laser diagnostics, for the first time in wildland fire research,鈥 he said.
Rieker, who is also in the Mechanical Engineering Department, said this is quickly becoming an important research area for the college.
鈥淚t is an important research area for our region as well,鈥 he said. 鈥淲e are now planning a new project in the WindCline involving five CU 麻豆影院-based investigators with others at Colorado State University, the Los Alamos National Laboratory and elsewhere.鈥
