Dynamics of Vortices and Shock Waves in Nonuniform Media.

Abstract

Instrumentation systems and measurement techniques have been developed for studying shock-produced vortex rings, and preliminary measurements have been made. The project is designed to focus on the mechanisms of turbulence production and damping in vortex rings and on the mechanisms of vortex-ring instability. These processes are currently of great interest in the effort to understand how large-scale, coherent motions which occur in vortex rings and shear layers contribute to dissipation and mixing at small scales. The work is directed at studying the properties of high-energy vortex rings prior to the occurrence of instability, and also certain characteristics of the instability as it occurs in very strong vortex rings.
