Dissipation of an Axially Symmetric Turbulent Wake in the Very Far Field

Author

R. H. Waser

Abstract

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.
