Abstract
The mechanism of vortex reconnection is investigated by solving the Navier–Stokes equation numerically starting with a closed knotted vortex tube, which gives a nonzero helicity. A new type of vortex reconnection mechanism—bridging—is observed. Small regions of high vorticity bursting out of the vortex tube become larger 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
