A study was conducted on three generic vortex ring configurations and found that in all cases the rings reconnect. In addition, an intensification of dissipation which was local in time and could be a mechanism contributing to turbulence intermittency was observed. Thus, a by-product of reconnection was the formation of stretched structures with antiparallel vorticity which transfer energy to the smallest scales where it was rapidly dissipated. Without this energy redistribution in wave number space the decay of global kinetic energy would be slower.
