论文摘要
我们通过直接的数值模拟显示，通过稳定加热浸入氦II的长圆柱体产生的湍流非常不均匀，由围绕圆柱体周围的量化涡流的密集湍流层组成。我们根据涡旋线密度和各向异性的径向分布分析了这种超流体湍流的性质，并将这些特性与通道中均匀的逆流湍流的较为众所周知的特性进行了比较。
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 analyse 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.
