Question
After rising a short distance the smooth column of smoke
from a cigarette breaks up into an irregular and random pattern. In a similar fashion, a stream of fluid flowing past an obstacle breaks up into eddies and vortices which give the flow irregular velocity components transverse to the flow direction. Other examples include the wakes left in water by moving ships the sound produced by whistling and by wind instruments. These examples are the results ofSolution
Turbulent flow is accompanied by random, irregular, local circular currents called vortices.
