摘要: Helium II at temperatures below Tλ can be described as a superposition of two interacting fluids. A normal-fluid which has non-zero viscosity, and an inviscid superfluid in vorticity is confined to quantised vortex filaments. These fluids are coupled together by the mutual friction force. To model flow we use forced Navier-Stokes equation while modelled motion lines. In this article describe numerical methods used for We also briefly discuss detailed structures observed from two-dimensional (2-D) three-dimensional (3-D) simulations problem.
