A wake visualization technique has been used to observe the turbulent wake at distances of 106 diameters behind an axially symmetric streamlined body traveling submerged in water. It has been found that a transition occurs in the rate of wake growth between 104 and 105 diameters which is attributed to a "reverse transition" from turbulent to laminar flow.
The wake visualization technique involves dropping a dye-coated body down a taut vertical guide wire into a large water-filled tank. Measurement of the wake growth and dissipation is made from a time series of photographs.
The bodies tested were 6 x 1 prolate spheroids of two sizes. Body density was varied to change velocities.
