Is anyone else here fascinated with fire like I am. I can sit and stare at fire for hours. I like to burn different stuff and see how it is consumed. Fire is just badass. And yes as a kid I started two fires at our local deadend that the FD had to come put out. One playing with matches and dead grass and the other playing with model rocket engines.

I think it would follow the fuel. Assuming youre not burning pure O2 in the cabin (bad BAD things) it would follow the fuel and burn the wood on the match. Sorry to burst your bubble. |
I know it would follow the fuel, but you know how when you light a match, the flame is shaped longer pointing up, and no matter how you turn the match, the flame is always pointing up? I was wondering what shape the flame would be. |
It would probably be very difficult to support ongoing combustion in zero-g due to the lack of a convective current drawing oxygen to the fuel, which is pretty much what you said. Here's a discussion on burning candles in space that confirms the spherical flame front. |
orb like burn but the fire would be fed oxygen since it is present in a pressurized environment. |
There have been film clips of experimental burns on the shuttle. As already assumed, it is a ball flame. But fire propagation is slow because without gravity and the resulting air pressure gradient, the fire isn't as rapidly fed with fresh air. |
+1 for a spherical flame. A team from my school flew on NASA's KC135 and tested flame propigation in microgravity and got those results |
Fire is awesome. The sheer destructivness is awesome. |
