Abstract

Numerical evidence is presented for the existence of collapse configurations of vortex sheets onedimensional singular distributions of vorticity in a twodimensional ideal fluid Point vortices are used to approximate the vortex sheets These and related motions cause a significant concentration of vorticity with possible relevance to the concentration seen in the evolution of turbulent flows
