Streamlines:
- Streamlines are a family of curves that are instantaneously tangent to the velocity vector of the flow.
- These show the direction in which a massless fluid element will travel at any point in time.
Streaklines:
- Streaklines are the loci of points of all the fluid particles that have passed continuously through a particular spatial point in the past.
- Dye steadily injected into the fluid at a fixed point extends along a streak line.
Pathlines:
- Pathlines are the trajectories that individual fluid particles follow.
- These can be thought of as "recording" the path of a fluid element in the flow over a certain period.
- The direction the path takes will be determined by the streamlines of the fluid at each moment in time.
