Potential flow
Potential Flow, also know as Incompressible Flow or Irrotational Flow in Fluid mechanics is flow defined by the equations
∇ x v = 0 (zero rotation = no shear)
∇ . v = 0 (zero divergence = continuity)
Equivalently,
v = ∇ 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.
