Back in 2012, during something called FLame Extinguishment Experiment (FLEX), astronauts on the International Space Station (ISS) discovered something that can only be described as cool flames. That would be flames that burn at low temperatures – up to 400 °C (752 °F), instead of the 1,200 °C (2,192 °F) one gets from say a propane blowtorch. And now they’ve done it again. 11 photos
Earlier this month, NASA announced the results of a test that recently concluded. Called the Cool Flames Investigation with Gases (CFI-G), it sought to create cool flames using gaseous fuels instead of liquid fuel, like it happened back in 2012.
As part of the Cool Flames Investigation with Gases (CFI-G) project led by fire protection engineer Peter Sunderland of the University of Maryland, attempts to light hot diffusion flames were made in zero-G for six months, but none morphed into cool diffusion flames after being snuffed out. “Cool diffusion flames require very low gas velocities because the chemistry is so slow,” Sunderland tells SYFY WIRE. “On Earth, even a candle flame generates velocities a hundred times higher because of buoyancy. We have recently seen some cool diffusion flames on Earth, but these require tricks like heated air and added ozone.”
