“…1. Several extrapolations of the slip theory for vibrating wires have been suggested, see Carless, Hall, and Hook, 15 Guénault et al, 25 and more recently by Bowley and Owers-Bradley 16 together with Perisanu and Vermeulen. 17 None of these have attempted to include the effect of the container or the Fermi-liquid interactions.…”

“…It follows from Eqs. (5) and (15) below that the first term in Eq. (3) contributes to Z proportional to ω 2 , and we neglect it.…”

“…The no-slip case in a cylindrical container was calculated by Carless, Hall, and Hook. 15 The case of perfect slip in unlimited liquid was calculated by Bowley and Owers-Bradley, 16 …”

“…Previous work has considered uniform bulk liquid 3,7-9 or one-dimensional geometries such as an oscillating planar wall in semi-infinite liquid [10][11][12] or Poiseulle flow between parallel planes. 13,14 For more general geometries calculations have been done only in limiting cases of small mean-free path [15][16][17] and in the ballistic limit. 16,[18][19][20] We start in Sec.…”

Anomalous Damping of a Low Frequency Vibrating Wire in Superfluid 3He-B due to Vortex Shielding

“…A similar device was recently used to probe the frequency dependence of grid turbulence [25] in superfluid 4 He. Here we describe measurements using conventional vibrating wire techniques [18,26,27] at the resonant frequency of the wire.…”
