In this paper, we study the influence of the boundary conditions of the velocity fields in superfluid helium counterflow experiments. To make progress, we perform numerical simulations where we allow a slip velocity of the viscous component at the walls, and observe how this impacts on velocity fields and density profiles of distribution of quantized vortices. We conclude that the presence of a slip velocity at the walls generates a more homogeneous vortex distribution throughout the channel.

平面逆流通道中的壁效应

在本文中，我们研究了超流氦逆流实验中速度场边界条件的影响。为了取得进展，我们进行了数值模拟，允许壁上粘性分量的滑移速度，并观察这对量子化涡旋分布的速度场和密度分布的影响。我们得出的结论是，壁上存在滑移速度会在整个通道中产生更均匀的涡流分布。
