Fire In Zero Gravity

Explain yourself!

Basically in a normal flame you have hot combustion products which are less dense than the surrounding air so buoyancy makes them rapidly move upwards. As this is happening they are cooling down and there isn’t enough time to complete combustion so soot is formed. Blackbody radiation from the soot is the characteristic orange part of the flame that we are used to seeing.

In microgravity there is no buoyancy-induced convection so what you see is a pure diffusion flame. That means that there is a thin interface in a sphere around the vaporized fuel stream where the fuel and oxidizer is perfectly mixed to make combustion take place. the fuel burns nearly completely without being pulled away by buoyancy effects, thus you just see a sphere of perfect blue flame.

Experience Zero Gravity

There are thousands of people that are exploring some of the most beautiful landscapes in the world. This chapter we will take you to Norway Switzerland and France where people are jumping cliffs as high as 6,000 feet.

Experience Zero Gravity will hopefully provide you with the feeling and the emotion that we feel when we think about the experience of Base Jumping in the most scenic locations of the world.
