Abstract

This work addresses the numerical modeling of vortex loops in superfluid helium after loop reconnection at various temperatures. Modeling was conducted within the vortex filament method using the full Biot-Savart equation. It was found that the dynamics of vortex loops substantially depend on the initial position of the loops, and that temperature affects the number and size of the formed loops, the amplitude of the Kelvin waves and their decay behavior as well as the velocity of motion of the loops and their separate elements. The time dependence of the distance between the nearest elements of the emergent vortex loop is described by the power law, with the power of 1/2 before and after reconnection.
