摘要：
We show by direct numerical simulations that the turbulence generated by steadily heating a long cylinder immersed in helium II is strongly inhomogeneous and consists of a dense turbulent layer of quantized vortices localized around the cylinder. We analyze the properties of this superfluid turbulence in terms of radial distribution of the vortex line density and the anisotropy and we compare these properties to the better-known properties of homogeneous counterflow turbulence in channels.
