Laboratory and Numerical Studies of the Effects of Shear on 3-D Vortex Evolution

Abstract

This report documents the results of ONR Contract N00014-01-C-0316. The goal of this study was to begin to understand the effects of vertical shear on the evolution of a vortex pair. Vorticity is always generated from a three-dimensional lifting surface. Behind this surface, the vorticity typically rolls up quickly into a pair of counter-rotating vortices. Since vortices transport mass and momentum, their evolution and persistence are important in naval hydrodynamics.
