Streamlines and timelines provide a snapshot of some flowfield characteristics, whereas streaklines and pathlines depend on the full time-history of the flow. However, often sequences of timelines (and streaklines) at different instants—being presented either in a single image or with a video stream—may be used to provide insight in the ...
Analytical methods that analyse a given flow and show properties like streamlines, streaklines, and pathlines. The flow can either be given in a finite representation or as a smooth function. Texture advection methods that "bend" textures (or images) according to the flow. As the image is always finite (the flow through could be given as a ...
File:Lagrangian vs Eulerian [further explanation needed] Eulerian perspective of fluid velocity versus Lagrangian depiction of strain.. In classical field theories, the Lagrangian specification of the flow field is a way of looking at fluid motion where the observer follows an individual fluid parcel as it moves through space and time.
The following outline is provided as an overview of and topical guide to fluid dynamics: . In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.
Why not give the streamlines as initial-value ODEs like the streaklines and pathlines? Also, it might be stressed that pathlines are spatiotemporal lines while streamlines are only spatial lines. — Preceding unsigned comment added by 62.16.179.14 ( talk ) 20:48, 7 August 2013 (UTC) [ reply ]

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.
