Fluid Dynamics
Flow
Motion with relative movement between fluid particles where continuous deformation happens.
Flow patterns
Streamline
A line tangential to the flow velocity.
Streamtube
A passage enclosed by a collection of streamlines.
Pathline
Path traced by an individual fluid particle.
Streakline
Suppose a dye is injected into a fluid flow. Streakline indicates the positions of all particles passed through the point of injection.
