Why does the rising smoke of an extinguished match-stick first experience turbulent flow and then laminar flow?
After a match-stick has been lit and then extinguished, the smoke that evolves firstly experiences a turbulent flow and then turns to a laminar flow. Can anyone please tell me why does this happen?
Actually, it is more likely to be first laminar and then turbulent. The turbulence develops gradually as the smoke rises because the farther the rising air column deviates from equilibrium, the more it is subject to force away from equilibrium. Eventually, it gets so far from equilibrium that it forms a swirl, and the lower part of the column then separates from the swirl and experiences a force toward the opposite side.
