Dynamics of Turbulent Vortex Rings.
Abstract
One of the major challenges facing engineers who deal with complicated flow systems is the question of how to analyze flow fields containing complex distributions of vorticity. Such flow fields occur in boundary layers and other shear flows and also in applications where mixing is a prime consideration, such as in combustors, chemical lasers, etc. It is often necessary to know something about the scale and geometry of the flow field, in addition to the mixing and transport. Unfortunately, vortex interactions are inherently long range and no local theory can yield the geometry of the flow or the distribution of the vorticity at any given location. Consequently, there is presently no approximate theory for treating vortex flows of complicated geometry. In order to provide information about the processes that are important in vortex flows, and to provide guidance for the development of theoretical models of these flows, it is important that experiments exploring the fundamental behavior of simple vortex flows be carried out.
