A new type of 'blue flame whirl' may be discovered and help remove spilled oil, etc.

A wide range of, fire, fire disaster in the updraft that occurred is born by swirling flames, such as wildfire

fire whirlwind terrible phenomenon, the inside of the whirlwind is in the ultra-high temperature state of more than 1000 degrees, which extensively harm is. However, a new type of fire whirl has been discovered by a research team at the University of Maryland and is expected to make a significant contribution to reducing carbon emissions and cleaning operations during oil spills.

A research team at the University of Maryland's A. James Clark School of Engineering was experimenting with how a fire whirl burns on oil floating on the water, and I happened to see it before. I found a type of fire whirl. During the experiment, the normal yellow fire whirl changed color to a blue fire whirl.

The actually confirmed blue flame whirl is generated around the yellow flame.

Only the blue fire whirl remained.

Professor Elaine Oran, who participated in the experiment, said, 'Incomplete combustion occurs when there is not enough oxygen to completely burn the fuel. Then, soot dust (fine particles such as soot) is generated, and this soot dust is generated by heat radiation. It emits yellow light and the flame looks yellow. The blue flame whirlwind discovered this time means that there is enough oxygen required for complete combustion, and there is less soot than a normal fire whirlwind. Or not at all, it means that clean combustion is occurring. '

The research team also suggested that a blue flame whirl could be a great help for combustion with high combustion efficiency and low carbon emissions, which are in high demand worldwide. 'Fire whirls have long been perceived as dangerous, but like electricity used to be, fire whirls could be used for the good of the world. We properly blue fires. If you understand the mechanism of the whirl, there is a good chance that you can control its power and use it, 'he said, revealing his expectations for the blue fire whirl.

One of the removal operations performed when oil spills into the sea is to burn the oil to remove it. In this case, air pollution can occur if proper combustion is not caused, but the research team argues that understanding the mechanism of the blue fire whirl will enable the burning of oil that does not cause air pollution. .. In addition, the high combustion efficiency of the flame whirl itself improves the efficiency of removal work. If the research team's claim is scientifically proven, even if oil spills into the sea due to an oil tanker accident, the impact on the environment will be minimized and removal work will be possible at a faster speed than before. That's why.

The research team also says that the blue flame whirl is useful for studying 'vortices' in fluid mechanics.
