Some General Characteristics and Properties of Three-Dimensional Flow Fields
The principal purpose of this paper is to draw attention to physical ideas, derived mainly from basic research in aeronautics, that seem to shed light on the structural forms taken by flow fields generated in the high-Reynolds-number motion of bodies through air. In particular, it is suggested that these ideas lead to the view that any such flow, however complex, can be regarded as a set of much simpler elementary constituent flows which, though they certainly interact with each other, tend to retain much of their individuality for considerable periods of time. Thus, the key to understanding the flow as a whole lies in the recognition of the structure and properties of its basic elements and of the kinds of interaction that can occur between them.
