Abstract
The mechanism of vortex reconnection is investigated by solving the Navier-Stokes equation numerically starting with a trefoiled closed knotted vortex tube. A new type of vortex reconnection mechanism–bridging–is observed. Small regions of high-vorticity burst out of the vortex tube. grow up and bridge different portions of the tube. A relation between the change of the helicity and the mechanism of the vortex reconnection is discussed.Keywords
