Streamlines are a family of curves whose tangent vectors constitute the velocity vector field of the flow. These show the direction in which a massless fluid element will travel at any point in time.

Three types of fluid element trajectories are defined: Streamlines, Pathlines, and Streaklines. They are all equivalent for steady flows, but differ conceptually for unsteady flows.

An important concept in the study of aerodynamics concerns the idea of streamlines. A streamline is a path traced out by a massless particle as it moves with the flow.

In steady flow, the fluid is in motion but the streamlines are fixed. Where streamlines crowd together, the fluid speed is relatively high; where they open out, the fluid is relatively still.

streamline Cultural The line traced by a liquid or gas as it moves. Streamlines are most commonly used in describing the flow of a liquid or gas around a solid object.

Apr 22, 2020 · Streamlines are imaginary lines that represent the direction of the flowing fluid at a certain point in time (the direction of flow velocity is tangential to the streamline).
