REVIEW OF THE VORTEX WAKE ROLLUP PROBLEM.
Abstract
The near wake problem behind an airfoil is reviewed in the context of some eighteen references, both theoretical and experimental. It is found that the body of theoretical literature makes an inconsistent approximation about the axial component of velocity in the flow. The techniques of selfsimilar hydrodynamics, vortex system theory, and conservation of energy arguments as they apply to the roll-up problem are discussed. Some important experimental evidence seems to confirm that the near wake problem is basically three-dimensional and should be reexamined as such. A paradox in the role of viscosity in the concentrating mechanism is discussed. (Author)
