Vortex - Wikipedia
A surface that is everywhere tangent to both flow velocity and vorticity is called a vortex tube. In general, vortex tubes are nested around the axis of rotation. It is only through dissipation of a vortex due to viscosity that a vortex line can end in the fluid, rather than at the boundary ... Read Article
