Abstract

Helicity produced by nearly singular vortex interactions is shown to play a role in the ensuing development of turbulence. This might provide a link between turbulence and the dynamics of the three-dimensional Euler equations. where numerical evidence has suggested that there might be a singularity. Interactions between regions of oppositely signed helicity in both physical and Fourier space are shown to be associated with the transfer of energy to small scales and the formation of vortex tubes, both being properties of fully, developed turbulence.
