Newtonian-like behavior of starting vortex flow in superfluid helium at high Reynolds numbers
J. Blaha, L. Xu, M. La Mantia
We study experimentally the starting vortices shed by airfoils accelerating uniformly from rest in superfluid helium-4 (He II). The vortices behave apparently as if they were movin…

Numerical study of vortices within a background vortex
Ling Xu
This study aims to exploit the analogy of vortex dynamics in a 2D ideal fluid and 2D non-neutral plasma. Numerical simulations using contour dynamics with adaptive refinement are c…
