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…
Asymptotic stability of planar rarefaction waves for 3-d isentropic Navier-Stokes equations under periodic perturbations
Feimin Huang, Lingda Xu, Qian Yuan
We study the asymptotic stability of a planar rarefaction wave (in the - direction) for the 3-d isentropic Navier-Stokes equations, where the initial perturbation is periodi…
Start-up vortex flow past an accelerated flat plate
Ling Xu, Monika Nitsche
Viscous flow past a finite flat plate moving in direction normal to itself is studied numerically.The plate moves with velocity , where . We present the evolutio…
Numerical study of viscous starting flow past a flat plate
Ling Xu, Monika Nitsche
Viscous flow past a finite plate which is impulsively started in direction normal to itself is studied numerically using a high order mixed finite difference and semi-Lagrangian sc…
