Potential Complex-Lamellar Decomposition of Fluid Flows

Abstract

Application of the potential complex-lamellar decomposition to the velocity field of a fluid flow was investigated. It was hoped that this decomposition would aid in understanding flows where both irrotational and vortical motions are occurring simultaneously (turbulence, aerodynamic noise, three-dimensional boundary layers). After considerable preliminary study it was found that the basic premise of the work was invalid. This result means that the flexibility of the decomposition is not as great as anticipated, and that further work on three-dimensional flows with viscous is not appropriate. Work on applying the decomposition to inviscid, vortical, three-dimensional flows (plasms) is being pursued by other researchers.
