By definition, different streamlines at the same instant in a flow do not intersect, because a fluid particle cannot have two different velocities at the same point. However, pathlines are allowed to intersect themselves or other pathlines (except the starting and end points of the different pathlines, which need to be distinct).
Operation Streamline is a joint initiative of the Department of Homeland Security and Department of Justice in the United States, started in 2005, that adopts a "zero-tolerance" approach to unauthorized border-crossing by criminally prosecuting those perpetrating it. Up to 70 people are tried at the same time, sometimes wearing shackles in the ...
Because = everywhere (e.g., see In terms of vector rotation), each streamline corresponds to the intersection of a particular stream surface and a particular horizontal plane. Consequently, in three dimensions, unambiguous identification of any particular streamline requires that one specify corresponding values of both the stream function and ...

Streamlines around a sphere in axisymmetric Stokes flow.At terminal velocity the drag force F d balances the force F g propelling the object.. In fluid dynamics, the Stokes stream function is used to describe the streamlines and flow velocity in a three-dimensional incompressible flow with axisymmetry.

In a stationary vortex, the typical streamline (a line that is everywhere tangent to the flow velocity vector) is a closed loop surrounding the axis; and each vortex line (a line that is everywhere tangent to the vorticity vector) is roughly parallel to the
Like a streamline, a stream surface is used to visualize flows – three-dimensional flows in this case. Specifically, it is "the locus of an infinite set of such curves [streamlines], rooted at every point along a continuous originating line segment."
