On the one hand, at reduced gravity, the flame looks very different from what you see here on Earth. The familiar shape we know is due to the way the flame's hot gases rise as gravity drags cooler, denser air to the bottom of the flame.
In microgravity, this flow does not happen, creating spherical flames. This image shows a flame snapshot in microgravity. Yellow spots are clumps of soot that glow yellow when hot; these become greater in microgravity than on Earth because the soot stays inside the flame longer.
The results of these experiments could allow the design of flames with more soot or no soot, depending on the need for a specific application, such as improving radiant heat or reducing the production of pollutants.
This image is one of many flames lit as part of the Flame Design research within Integrated Rack Combustion, which is designed to safely perform combustion experiments on the International Space Station (ISS) without risk to the spacecraft or its crew. .. With a large share of electricity in the US. USA Generated by combustion, learning to make cleaner or more efficient flames can have an impact in many areas of our lives.
