Hello,
Temperature of sources is 300C and surrounding is set to 0C and this difference is all that matters for buoynacy.
It would be the same as having 300K source and 0K ambient temp.
So, from the buoyancy standpoint - it's practically the same if it's 300C or 300K as long as ambient is 0.
..although, from the physical point of view - 0K is absolute zero and not present anywhere is the Universe, so I
hope they're using some more appropriate surrounding temp like 273.15K with is 0C. In that case,
buoyancy in PhoenixFD would be about 10 times weaker than in FumeFX.
Phoenix (300 - 275.15) vs FumeFX (300 - 0).
In real world a source with temperature of 300K wouldn't cause any buyancy as this is very close to room temperature.
Best regards,
