The velocity fields of three-dimensional viscous wakes with small swirl and streamwise pressure gradients are examined with the use of the boundary layer approximations, Ossen's linearization of the convective terms, and the assumption of constant fluid properties. Transform methods yield mathematically exact solutions with general types of initial conditions. The theory, while applicable to many practical problems (such as describing the phenomena in a tip vortex), is not applied here an its application is left for future investigation.

The existence and crucial role played by large-scale, organized motions in turbulent flows are now recognized by industrial, applied and fundamental researchers alike. It has become increasingly evident that coherent structures influence mixing, noise, vibration, heat transfer, drag, etc... The accelera tion of the development of both experimental and computational programs devoted to this topic has been evident at several recent international meet ings. One of the first questions which experimentalists or numerical analysts are faced with is: how can these structures be separated from the background turbulence? This is a nontrivial task because the coherent structures are gen erally embedded in a random field and the technique used to determine when and where certain structures are passing, or their averaged characteristics (in the more probable or dominant role sense) is directly related to the definition of the coherent structure. Several methods or approaches are available and the choice of a particular one is generally dependent on the desired informa tion. This choice depends not only on the definition of the structure, but also on the experimental and numerical capabilities available to the researcher.
