Potential flow

'Potential Flow, also know as Incompressible Flow or Irrotational Flow in Fluid mechanics is flow defined by the equations

&grad; ✗ v = 0    (zero rotation = no shear)

&grad; ˙ v = 0      (zero divergence = continuity)

Equivalently,

 v = &grad; Φ

 v vector fluid velocity
 Φ fluid flow potential, scalar

Together with the Navier-Stokes equations, these equations can be used to calculate solutions to many practical flow situations.
