Stokes stream function

Stokes stream function

[′stōks ′strēm ‚fəŋk·shən]
(fluid mechanics)
A one-component vector potential function used in analyzing and describing a steady, axially symmetric fluid flow; at any point it is equal to ½π times the mass rate of flow inside the surface generated by rotating the streamline on which the point is located about the axis of symmetry.
