It may sound unreal, but astronauts on the International Space Station have managed to create strange cold flames in microgravity, and they even have photo evidence. Combustion engines will benefit from this progress, and our planet will benefit too.
Despite the contradiction in the two words’ alliance, the cold flame was indeed real. Well, the name is a bit misleading, because their temperature is still up to 400 degrees, but it’s really lower than the temperature of a typical flame. .For example, the temperature is between 800 and 1400 degrees. It’s rare that Cold in everyday life, but astronauts from (ISS) achieved this,
In 2012, cold flamesCreated on the International Space Station, liquid. In 2021 as part of the project Gas cold flame check (CFI-G), the researchers were able to recreate the same thing, but this time using gaseous fuels. This was the first time the cold flames were spherically scattered Gas, realization has never been simpler. It is a unique phenomenon that is difficult to reproduce on Earth.
In microgravity, flames burn longer
On the ground, likeBurns, its by-products keep away from flame . Under ISS conditions, they remain close to each other, which allows the reaction to be reused, and thus last longer. In addition, there is no Heavier or lighter on the station, so the flame does not have the same shape as on the ground.
The goal of studies on cold flame is to better understand them and model their performance. Using them successfully on Earth will allowto me Improvement. In fact, the use of low temperature processes will make it possible and engine wear, while increasing fuel efficiency. In the context of space exploration, in-depth knowledge will make it possible to assess the risks of using cold diffusion flames in ships, to better manage fires there, or ideally, .
