COLLEGE PARK, Md. -- Fire tornados, or 'fire whirls,' pose a powerful and essentially uncontrollable threat to life, property, and the surrounding environment in large urban and wildland fires. But now, a team of researchers in the University of Maryland's A. James Clark School of Engineering say their discovery of a type of fire tornado they call a 'blue whirl' could lead to beneficial new approaches for reducing carbon emissions and improving oil spill cleanup.
A new paper published online August 4, 2016, in the peer-reviewed journal Proceedings of the National Academy of Sciences (PNAS) describes this previously unobserved flame phenomenon, which burns nearly soot-free.
