Streamlines fluid mechanics
Streamlines, streaklines and pathlines are field lines in a fluid flow. They differ only when the flow changes with time, that is, when the flow is not steady. Considering a velocity vector field in three-dimensional space in the framework of continuum mechanics, we have that: Streamlines are a family of curves … See more Streamlines Streamlines are defined by $${\displaystyle {d{\vec {x}}_{S} \over ds}\times {\vec {u}}({\vec {x}}_{S})=0,}$$ where "$${\displaystyle \times }$$" denotes the See more In steady flow (when the velocity vector-field does not change with time), the streamlines, pathlines, and streaklines coincide. This is because when a particle on a streamline … See more Knowledge of the streamlines can be useful in fluid dynamics. The curvature of a streamline is related to the pressure gradient acting perpendicular to the streamline. The center of curvature of the streamline lies in the direction of decreasing radial … See more • Streamline illustration • Tutorial - Illustration of Streamlines, Streaklines and Pathlines of a Velocity Field(with applet) • Joukowsky Transform Interactive WebApp See more Streamlines are frame-dependent.
