An experimental investigation of mean and fluctuating
mixture fractions and velocities within fully-developed
round turbulent plumes is described. This problem is of
interest as a classical buoyant turbulent flow that is
relevant to flows found in fire environments.
Conditions within the fully-developed, or
self-preserving, portions of the flow were emphasized,
where both mean and turbulent properties exhibit
similarity when variables are scaled appropriately.
Such conditions are helpful because turbulent flows is
faciliated because effects of extraneous source
disturbances have been lost.
